If they feel main drains are not required that brings their marketing/ sales practices into question.
The suction cups on the bottom
they use the suction thingy on their bottom.
Call a plumber
I had an inground pool installed. We just turned on the lights at night and noticed footprints on the bottom. Can this be fixed? Call the pool company back. The bottom is normally sand mixed with cement. The liner will probably have to be removed and bottom smoothed. They should have checked that before installing the liner. Those printswi catch sediment and debris for the life of the liner.
They are called 'tube feet'.
Personally, I'd call a pool company.
Have the pool drained and acid washed.
the suction cups on the bottom of their body help them get a good grip on things.
suction cups that help them grab their food.=) XD
No, Starfish don't do much. Starfish lie on the bottom of the ocean floor, Although they are like suction cups they can suction to you hand. No aggression I see in a Starfish at all.
To remove excess rain water in an inground pool, you likely want to get a filter. You can also install a drain at the very bottom of the pool, but this will need to be closed if there were water in the pool for swimming.
No the momment you throw it in the water it would short out and shut off. With out suction it wont be able to stay at the bottom of the pool.
Hydrostatic pressure or poor water chemistry. If the watertable is high the liner will float and when the water recedes will create a suction and pinch the liner. If your alkalinity and stabilizer levels are low the sanitizer will not have any molecules to attach to so it goes after the vinyl. The pulls the plastizer out the vinyl and causes it to prematurely fade and wrinkle.
Call a local pool store and ask what they recommend in lieu of draining the pool.
you shouldn't be plugging any holes at the opening! that's when u REMOVE plugs. If you meant pool closing you plug the one that has the suction. usually one of the 2 holes is caped off a few inches down. Only one hole runs to the pump.
Kind of, mice have about 5 or so suction cup like pads on the bottom of their feet, which enables them to climb easier although the sticky pads or suction cups aren't very strong,especially if they were to be holding onto something upside down.
lift out the skimmer basket there should be a floating diverter with a flap that closes off suction. some skimmer baskets are rotated to do the same thing. insert your hose into the other skimmer. turn off suction to the main drain if you need more suction.
Vermiculite is not a suitable substrate.
i just drained mine and it was at the bottom of the rad
You can get a by pass valve that will alleviate some of the suction by taking water into the hose at another point.
Yes it can be done
Take the screw out of the bottom of the sump until enough has drained then put it back.
the concrete should be 6" according to this site http://www.de-fontenay.com/poolcon4.htm
