FAQ - Swimming Pool Main Drains

What is swimming pool entrapment entrapment? There are five forms of entrapment. They're easy, yet essential to understand to "get" this whole issue. 1. Body entrapment (a section of the torso becomes entrapped). 2. Limb entrapment (an arm or leg is pulled into an open drain pipe). 3. Hair entrapment or entanglement (hair is pulled in and wrapped around the grate of the drain cover). 4. Mechanical (jewelry or part of the bather's clothing gets caught in the drain or the grate). 5. Evisceration (the victim's buttocks come into contact with the pool suction outlet and he or she is disemboweled.) How can I drain my pool without a drain? The funny thing is, drains are hardly ever used to drain a pool! How goofed up is that?! TWO big points to remember: 1. With a composite fiberglass pool, there is no need to empty your pool for general maintenance as you would with a concrete pool. But if you ever did want to drain your pool to add say, a pretty tile mermaid mosaic like we did in our pool, all you have to do is use a sump pump or open your filter plug. That's what a pool professional would do. A sump pump is the quickest, most efficient way to drain a pool. So no, you don't need a drain to drain your pool. The "drain" in your pool is not like the drain in your bathtub! 2. Remember---NEVER drain your pool yourself. Always consult with a pool professional. Issues involving hydrostatic pressure could really mess up your pool and deck area. So what is a drain in a pool if it's not like the drain in my bathtub? A pool "drain" is actually a misnomer. A pool doesn't drain anything. That drain is really a suction outlet. It's sucking water out of the pool and taking it back to the filtration system, then back again to the pool. It's like a straw. And the pump is like you. Entrapment is like when you're sucking up that strawberry shake from Dairy Queen and nothing comes up---then you quickly discover a strawberry "entrapped" at the end. Stop sucking and the strawberry releases. Your pool requires a powerful pump to "pull" that liquid back to the pump. So why in the world would you want that "outlet" for suction inside your pool where those sweet babies of yours are swimming? Then how do you get water to the pump without a "suction outlet?" Good question! The water comes byway of a wonderfully, brilliant little device known as a skimmer. A skimmer is a gravity-fed product that simply collects water from the pool via gravity and simultaneously skims out leaves and gunk. It then deposits the water into a pipe that is connected to the pump. The pipe is completely unreachable by swimmers. No one ever sees the pipe that goes to the pump, which is housed deep inside the skimmer, below the crud collection basket. So there you have it. Easy breazy water collection without a bit of danger. I had another builder tell me that if we didn't have a drain system, our pool would not circulate properly. This is another one of the biggest objections by pool builders for not having "bottom suction" in a pool. The scary thing is, it is the least understood. It is based on the "belief" that water becomes stagnant in the deeper areas. It is not based on science. For some awesome science on this whole concept, the must read here is the Fluent / Trilogy Pools study on pool circulation. This study clearly shows that drains not only are unnecessary, but they do not improve the circulation in a pool or enable its ability to clear contamination. Imagine that! Aren't dual drains safe? Yes. For the most part. BUT, the real question is, would you rather have your loved ones swimming in a pool that is safe "for the most part" or in a pool that is 100 percent safe? Here's the deal. Systems fail. That is why Florida requires "layers of protection." In the event that the second drain fails, a vent line or a suction vacuum releif system will release the suction and release anyone stuck on the drain. That's just great until the vent line gets clogged with yard clippings or rodent, or the svrs runs it's life expectancy. (Have you ever heard of an appliance that doesn't eventually fail?) Plus then there is the issue of the drain covers. Guess what happens to plastic in a chlorinated environment. You guessed it. Corrosion. The screws become loose eventually and the plastic gets all funky. Now you have drain(s) that have loosey-goosey covers that were supposed to be protecting you from the last 3 forms of entrapment. Yikes, and to think you didn't even need those drains in the first place. See how frustrating this is? I want a spa and a pool builder told me I had to have a drain in my spa in order for it to run properly. Can you build a spa without a drain? Absolutely! In fact the spa is the most dangerous place for a drain. Because a spa is typically only 4 feet deep, where do you think all the kids like to congregate? It's the most fun for kids to goof around in a little warm body of water, and guess what they do? Yep, they investigate the drain(s). They're easier to get to in a spa that's for sure! We have built many, many pool/spa combinations with no drains. The reason a pool builder would want to use a drain is because they need to supply the pump with water and a bottom suction seems to be a great place to get it. The thought of using skimmers on a spa is foreign. We use multiple small skimmers and supply our pump the same way we do our pools---through a gravity fed system. Our spas circulate beautifully and have zero hazard. You can have a 100% entrapment free pool. Expect your builder to understand this concept. If he/she does not, please contact someone who can assist you. There should be no more entrapment deaths.

Outdoor Solar Lighting - Stylish, Green And Cheap

Outdoor solar lighting can add many different effects to the outside of your home. It can be used to create silhouettes, shadows, down lights or crossing. The silhouette look would be one that you would consider if you wanted to light up a tree or a statue, basically anything that you would want to highlight but the solar lighting would be placed behind the item creating a silhouette. How To Create The Lighting Effects Shadowing would be created by placing the solar lights in front of whatever it is that you are looking to accent, such as a garden. Down lights would actually be hung and faced down to create more of a lamp post look and this would be more for security purposes. And crossing would be the effect if you placed solar lights that literally crossed in opposite directions. Solar lights work really well for this type of set up because they are brighter. Outdoor solar lights also work well for lighting up walkways as well as garden accents. The best thing about this method of illumination is that it costs nothing but your initial investment. The solar panels are powered from the sun in the day and automatically lit up at dark. They work from the energy that they absorb from the sun. They are low maintenance, they cost nothing to run, and you do not have to worry about turning them on or off. Caring For The Environment As the world is going green, these solar lights lead you right into that direction by being truly environmentally friendly. Solar lighting looks great when incorporated into any garden or landscape. They are so easy to install that you could literally let your child do it. You buy these lights in sets or pairs - simply decide how many that you will need and just stick them in the ground like a tent stake. There are other types of outdoor solar lights too. There are solar powered post lights that are also powered by solar energy and are connected to a post. There are also solar powered lamp posts, solar post lighting, and solar spot lights which are usually used for security measures. Limitless Power From The Sun If you are still unsure then consider this environmental fact, every hour the sun radiates enough solar power to supply the world's population with the same amount of energy that it is currently using in an entire year. That's pretty amazing! So the lighting system collects and stores energy from the sunlight during the daytime, thus recharging the lithium batteries that run it. You will notice with solar lighting that if you have a couple extremely cloudy days that the solar lights will be a bit dimmer but after a nice sunny day they will perk up like just watered flowers. Outdoor solar lighting is safe, environmentally friendly and even stays on during power outages. There are also garden and patio lights that are available using solar power. These lights can be easily moved with virtually no effort and will stick around forever and will do so with absolutely zero maintenance.

Investing in China's Energy Security Crisis, Part Two

Having been a previous director of Far East Energy, Tunaye Sai was able to develop his own connections in China. This led to his negotiating the Guizhou CBM concession in south central China � again another enormous block of 970 square kilometers � which was acquired by Canadian based AsiaCanada Energy. This became a wholly owned subsidiary of Pacific Asia China Energy, of which he serves as President and which began publicly trading on the Toronto Venture Exchange, this past January (TSX: PCE). His concession was the first awarded to a Canadian company by the Chinese who had previously only dealt with U.S. and Australian-based companies. Since then, China has awarded concessions to three additional Canadian companies. Again, the potential gas content of these concessions is staggering. In the case of the Guizhou concession, it could conceivably host a high-case scenario of 11.2 trillion cubic feet of gas. In an interview we conducted with Eric Nuttall, CBM research analyst for Canada�s Sprott Asset Management, he estimated for each trillion cubic feet of gas, a company might anticipate a market capitalization as high as $1 billion. Most CBM companies developing prospects in China, such as Far East Energy and Pacific Asia China Energy, are likely to be somewhat discounted because of country risk. Not so for Green Dragon Gas, which this past week listed on London�s AIM market (GDG), with a market capitalization of US$525 million. It placed just under six percent of its shares to raise $22 million. Green Dragon holds five production-sharing CBM contracts covering some 1.6 million acres in Fengcheng and Shizhuang provinces. It is estimated their holdings may host 16.6 trillion cubic feet of CBM gas. It appears the European investor is savvier to China�s prospects than those in North America. This was echoed during an interview with Pacific Asia China Energy executive vice president Steve Khan, who told us, �When we visit the London fund managers, they don�t have negative or a lesser view of China. They look at it as a great opportunity and they�re investing more funds there.� The nuances of investing in natural gas or CBM plays outside of North America may escape some investors. Not many realize that all gas is local. For example, natural gas sold at the wellhead in Australia or the Middle East is a fraction of the cost sold to England or in North America. While companies developing CBM resources in China carry a discount to their North American counterparts, pricing in the Chinese gas market is more stable. We talked with Resource Opportunities editor and geologist Lawrence Roulston, who told us, �I think the companies which are able to effectively exploit the CBM technology in China are going to be the pioneers in that area.� To date, less than 30 concessions have been awarded to foreign-owned companies by CUCBM. There have been rumors flying that another five to ten may be awarded in the coming year. As is often the case in China, the bureaucracy moves slowly � CUCBM began awarding CBM concessions in 1998 in the form of production-sharing contracts. Treated like winning lottery tickets, on average less than four per year have been handed out. CUCBM keeps between 30 and 40 percent of the production contract, and the development company pays all of the exploratory confirmation costs prior to production. Again it is about having connections with the right people in China. Roulston explained, �I could walk into the Petroleum Club in Calgary, and meet a half dozen guys and talk to them. I could build on my leads, and probably in a day be talking about a deal. When you go into China, unless you have somebody on your team that can get into the system and deal with the people, because of language issues, cultural issues and just having access to the information and knowing what sort of terms that they might be looking for.� He concluded, �If I was to go over to China and try to do a deal to get access to a coalbed methane property, I wouldn�t have a clue about how to begin.� That�s what separates the companies who�ve begun their CBM projects in China and why they could have outstanding long-term prospects.

How to Use Alternative Energy at Home

About solar power. Solar power is becoming much more widely available for the home consumer and as a consequence solar powered lights and solar powered features can be seen in many gardens and even in houses but often they have their limitations. Nevertheless solar power is still a viable energy source for your home and personal needs. There are grants available to have PV tiles fitted to your house as well as the grid tie systems that are associated with them. If you haven�t already looked into solar power as an alternative to buying all your power from the grid then do a little research. Not only will you be doing your bit for the environment but will it might just save you money on your energy bills. About PV tiles. Photovoltaic tiles are solar tiles used to transform the heat from the sun into electrical power and are becoming much more popular all around the world to power homes as well as heat water, heat your house or to heat your pool. Governments are beginning to offer grants to interested households and they are doing this as part of their commitment to producing more energy from renewable sources. Photovoltaic tiles are available that look almost identical to normal roof tiles and with the grants they aren�t much dearer, if they�re any dearer at all. Having PV tiles fitted means you can either use the heat collected to warm your house, warm your pool or even to create electricity to power your house. Grid tie systems. If you have PV tiles fitted you should also get a grid tie system. This means that you can actually sell your unused solar power back to the grid, meaning that in summer months you might not just save money but you could also be making a small profit. You only need a small amount of machinery attached to your tiles and virtually any loft has more than enough room to store the transformers and other equipment required. Other renewable energy uses around your home. As well as using PV tiles there are other factors. If you are really eco friendly there are small wind turbines available that will produce energy for your home but the present level of technology means that much of the initial energy created is wasted before it can be turned into a useful power source. You can collect rainwater using rain butts and use it for watering your garden or for cleaning your house. While this doesn�t create energy to power your house it will mean that little bit less stress on your local reservoir.
