If you have a sand filter, the filter is passing sand back to the pool. Have installer check the diverter and laterals inside the filter.

Yes, you'll get the power from the timer. First, find out if it is 120 volt or 240 volt (most pool pumps run 240v and most salt systems are set up default @240.) Second, find and turn off the circuit breaker to the timer and pump, usually a double 20 Amp breaker. Third, hook up salt system power supply wires to the LOAD side of the timer (2 AND 4) or (2 OR 4) if the pump is wired for 120v. Ok, so when the timer is turned on, then and only then shall the salt water system be powered up. If you're not too sure about electrical stuff like this, call an electrician. Most of these salt water systems will have diagrams that are easy to read and understand. I hope this helps you.

Sounds like your filter is short cycling. What size filter TR-60. 100 or 140? How old is the sand and just how much dirt is coming off of the bottom of the pool?

If that lid is on tight and still spits water just replace it and clean the living daylights out of all that old gunk around the lid and pump pot.. When you get it to prime again pay close attention to the valve in front of the pump (usually a three way Jandy valve.) Lean down and listen for any sucking noise. You won't see water leak when it is running but when you shut the pump off watch the center of the valve handle. If it spits a little water, you'll need to either replace the o-rings or the diverter. Don't forget the nipples that thread into the front of the pump. Those schedule 80, male adapters or CPVC nipples will shrink if the pump runs dry or had ran dry for too long. You may be able to see water squirt out between the front of the pump housing and that nipple when you shut it off. Sorry if I am rambling on, hope this helps you.

Sounds like you either have rips or tears in the grids or the manifold that hold the grids in place is cracked. A brand, model and estimated age would help narrow it down. Either way, you'll need to take the filter apart to find the culprit. If you're not sure about digging into this kind of project, call a pool repair company.
