I have been useing the Intex 1600 sand filter all season without any problems. Last week I hooked a fafco 4x20 solar panel to my pump. All week I have had silica sand in my pool. I assume it has something to do with the solar panel as all was well before it's install.
Details: pool has been vacuumed to filter many times over the past week. Yesterday all was vacuumed and a thorough back wash/rinse with a small amount of DE was added. This afternoon pool looks the same as yesterday. Maybe a 1/4 to a 1/2 cup of silica sand on the pool bottom after the pump/solar panel ran 6 hours.
PSI with the solar on is in the "green zone" of the pressure gauge, around 4 PSI.
Is there anything I can inspect on the filter to see if it is failing?
Could pressure from the panel cause the sand to leak? From the small amount of sand in the pool it looks like it is just leaking sand on start up of pump. If it was leaking sand for 6 hours there would be much more than the 1/4 cup or so there is on the pool bottom.
I will have time to trouble shoot it this weekend. With a clean pool bittom I will run the pump without the panel and again with the panel but just for a few minutes. Maybe this will help show what the culprit is and when it is occurring.
Any suggestions for trouble shooting or fixing the problem would be appreciated. Thank you.
