    dry well pumping

    We had a inground pool put in last summer. They installed a culvert pipe to serve as a sump. We have had a ton of water running into pipe requiring constant pumping whenever it rains. With the snow melting the last few days we are again pumping alot. They didn't hit water when they were digging pool so we can't figure out where water is coming from. Is this going to continue forever?

    Re: dry well pumping

    As long as the water level in the sump is at least one foot lower than the water level in the pool you don't need to do anything, no pumping, nothing to worry about. You really need to pump water out of the sump when it is above the water level in the pool, which typically only happens when you are draining the pool for some reason, though it can potentially happen if you are getting really extreme amounts of rainfall.

    Ground water levels vary dramatically at different times of year. It is not unusual for the sump to be dry for much of year and only have water in it part of the year.

    Possibly. the water is seeping into the sump from somewhere ABOVE the current level of the water in the sump.....in other words it is flowing downhill through the earth and collecting in the sump. That is the purpose of the sump.

    As long as water is accumulating above the sump level, it will continue to flow down and into the sump. Your PB must have known the need or they would have not put the sump in.

    Thanks for the help. We were told to keep water in crock under a foot, which is next to impossible, otherwise the liner will get wrinkles in it or float up. If it was this terribly important we thought they would have made us buy a overpriced pump as a scare tactic.

    I am not sure why it is nearly impossible but I am almost certain it is VERY important....I don't understand about the "overpriced pump".

    Re: dry well pumping

    Actually, you might enjoy hooking a sump into your main filtration system so that you can reverse it, though its still a manual proces, but simple/quick to do once built. The auto pumps aren't great because the burn out and then are expensive to access/replace. So with a reverse system, the rule of thumb our guy gave us was pump any time you've had about 3 inches of rain over a couple of days.

    If the water level in the sump gets too high it will indeed cause the liner to wrinkle. However the height above which you are likely to start seeing problems should be about one foot below the pool water level. How far below pool water level is one foot of water in the crock?

    About 3' below pool water level.
