Dig it up.
there is probably something in the pool that got into the pump
No
Yes, you would actually prefer to use it when the pump is running
Certainly, if the pump is running. The primary pump intake is the main drain at the deepest part of the pool.
check the filter
This could be from 3 yrs to 20 yrs. depending on brand and the conditions in which the pump is running.
So long as there is water coming through the pump when it is running it doesnt matter what the water level in the pool is.
YES THERE IS A LOT OF TRASH THAT CAN GET IN THE VALVE TO MAKE IT LEAK. YOU MIGHT BE ABLE TO CLEAN IT FURTHER I found that with the pump running, the pool water was rising as apparently the pump was pulling water out of the ground. This was with the pool water low and the skimmer plugged off in order to try to filter after a bad storm. When I shut off the pump, the pool water went down as the valve did not seat properly.
yes, pool water clean chlorine make
They probably did not install a pump underground(to pump ecsess Water) so when it rains alot or the ground is saturated your pool liner streches. Most vinal pool companies dont.
You will have to dig out underneath the pool and set a line underneath the bottom. You then attach this line to a pump. While you are building the pool you must keep this pump running.
The first pump fills (1/10th) of the pool in 1 minute.The second pump fills (1/15th) of the pool in 1 minute.With both running, they fill(1/10 + 1/15) = (3/30 + 2/30) = 5/30 = 1/6th of the pool in 1 minute.They have to run for [ 1 / (1/6) ]= 6 minutes in order to fill the pool.
