The average vinyl lined ingound pool is 18' x 36'. The cost of this pool averages $25,000 in the Southern US.
If the pool is 8 feet in the deep end and 3 feet in the shallow end, the total volume will be about 21,722 gallons of water.
It sounds like there is a broken water line under the sand. Perhaps from a sprinker system?
You can get a by pass valve that will alleviate some of the suction by taking water into the hose at another point.
Heaters are usually plumbed in after the filter. The pool filter/pump is what circulates the heated water. Ans: The heater will not work or fire if the pump is not running.
Yes, my neighbors did it... it was not "easy", though. First the pool builder came in with jack hammers, and "pocked" the entire surface. My neighbors chose to convert the pool to a self-cleaning pool, so after chiseling the surface, the builder installed the self cleaning gear before pouring the new pool interior, so the pool lost about 4 - 6 inches in depth. Made a beautiful pool and was done in just a few days.
i sewed the broken rope with 100lb test line to nylon tab. Works.
A broken blood vessel on the foot, or any other part of the body is simply a bruise. Bruises are cause by blood vessels that have broken, causing blood to pool under the skin.
You should have NO D.E. going back into the pool when you vacuum or anytime else. If you do have it going back in, you need to open the filter and check to see what part is broken, loose or missing.
Other than the wind blowing, nothing. If you cannot get rid of sand in your pool, it is most likely a filter issue. If you have a D.E. filter, and all the grids look good, check to make sure the manifold has a good seat. There is also a small "filter" on the top that may have a hole in it, if its crushed that is most likely your culprit. If you have a sand filter then you most likely have a broken lateral (a small line in the bottom of the filter that screens out sand) The only way to check these are to remove the sand and visually inspect all the laterals.

Salt water pools have their own chlorinators built into the system. However if this is broken down or under performing you can augment it with any sort of pool chlorine.
