    Losing water at filter

    This is the second time in a few weeks that this has happened. Woke up this morning and noticed the pool water level went down at least 1 inch overnight. This was significant since the water level was already very low, at the minimum level for the skimmer to properly function. I also have a bottom drain in the deep end and had the pump running overnight, 1/2 skimmer and 1/2 bottom drain.

    Went over to the pump/filter and notice a slow trickle of water coming out of the backwash/waste hose (blue hose in picture). Turned the pump off and spun the filter valve around to re-seat it in the "filter" position. Turned the pump on and water going even more quickly into the backwash hose! Turned off again, re-seated the valve handle on "filter" again, turned back on. Now no water is coming out of the backwash/waste hose and all is OK. Filling pool with water from garden hose right now to get level back up to normal.

    Here is a pick of the setup. Do you think it is a bad valve on top of the filter?

    Most likely a bad spider gasket. You probably just need to get a new one and replace it.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
