I'm replacing the sump basin/liner in my home which is currently a perforated 5 gallon bucket surrounded by gravel. I have an interior drain system that has two pipes terminating into the gravel pit area (but not into the basin itself - the water dumps into the gravel and through the holes in the bucket). We have a high water table and the sump runs every few minutes on normal days.
My question is: should I replace the bucket with a solid liner, with openings for the drain pipe to go directly into the basin to be pumped out.... or should I use a perforated liner that allows water to come in in addition to the drain pipes? It seems counter-intuitive to me to have the drain pipes empty into a basin with holes in it... but maybe I'm missing something and water needs to be allowed in in addition to the drains?
I really appreciate any advice you can give. Thanks!
Oh my - two very different responses! My thought was that if it the liner is sealed any additional water pressure would result in the perforated drain tile doing it's job "better" and bringing the water to the pit. However, the response from Ed was exactly what I'm concerned about (the ground water causing the floor to leak).
If I use a perforated bucket it would surely always have water at the bottom because of the high water table. Would it be okay to elevate the sump in the pit (using something like pavers) so that it's only emptying to a depth around 6" below the slab? The problem now is it's constantly cycling to remove ground water that is over a foot below the slab. I'm using a Zoeller without an adjustable float, so raising the pump itself is the only thing I can think of.
Thanks again for the responses.
Edited to add photo of current setup. The current bucket top sits a couple of inches below the top of the slab... when I install the new basin I will make it level with the slab and fill with concrete.
