When my pool was installed, there was no ground water present when they dug the hole. Due to rare heavy rains recently, the excess groundwater caused the liner to float and when the water receded, the liner is wrinkled in many spots. I am looking for a permanent solution to keep the groundwater from rising up in these rare occasions. What is the proper procedure to add a dry well (50-100 gallon) to the deep end of in-ground vinyl liner pool after the built is already built and all the masonry work is complete. Is it as simply as removing the liner, digging the hole for the drywell in the deep end, adding the plastic dry well and surrounding with stone, fixing the vermiculite/Portland cement base and then re-installing the liner?
Dry Well - In-ground Vinyl Liner Pool
- Thread starter Tom D 2012
- Start date
In my *fiberglass* pool the dry well is about 6" behind the deepest end wall. If you look down it you see stones that actually continue on to the stone bottom under the pool.
IF we had heavy ground water to worry about (and I never have) we would see water in the dry well and drop a small sump pump down to drain it off.
I know there are ways to put French drains around vinyl pools but I'm unsure if that is something that can be done after the fact easily?
I know this may not be very helpful, but I'm sure someone else will chime in.

Floating liner question
We got hit with massive rain for the last week and my liner floated. I have been gently and slowly coaxing it back into place all morning. The shallow end is back under water but still floating. Can I turn the pump back on to start filtering or should I wait? I have everywhere else back into...

Floating Vinyl Liner - After massive rainfall
I live in South Central Kansas and we had 4"-6" of rain in about a 6 hour timeframe overnight. When I woke up this morning, the pool was completely full and the liner had come undone in the corner allowing water to get in behind the liner (see attached pic). For reference, this is a brand new...

French drainage, drainage around pool?
Hello Everyone, I am contemplating adding some drainage around my pool and would like your thoughts. Our backyard slopes downward where the pool is. So there is about a 3ft drop from the back of our house to one side of the pool which is 20ft away. I would like to address this runoff and an...

what happens if my inground liner over fills due to rain?
We're getting monsoon rains and I already drained 3" of water saturday. Woke up this morning and the water level was 1" away from touching the T-track. Would water get behind/under the liner and cause me major trouble if somehow the rain over filled my pool? I do have french drains all around...

That is helpful.
How deep is the deep end of you pool and how far does the drywell pipe go down? My pool deep end is 6 feet deep so I was thinking to put a dry well pipe that is 8 or 9 feet deep and 8 inches in diameter in order to be able to put a submersible pump in in the event of very heavy rain that would cause groundwater to rise excessively.
