Our inground pool has been open 2 weeks. Sand Hayward filter S210t. I have been running my filter 12-24 hours a day to try and get my pool from green to blue. I have had 5 separate occasions, that within 1 -2 hours, my water level drops 1-2 inches. What could this be?

Need more information. Do you have an automatic overflow? How old is the pool? Solar heater? Have you checked for water puddles around the pool (grassy areas)?

Welcome to posting on the forum!
Type of filter? Do you backwash? Type of valve on the filter?

What is an automatic overflow? No heater and no obvious puddles, but this would be difficult because of the concrete around the pool

My concern would be that the MPV spider gasket may be leaking (intermittently?) and you are losing water to backwash while in the filter setting.
When you find a sudden water loss, check the 'woods' and see if it appears water has recently exited that area. 2 inches is likely several hundred gallons of water.

OKAY……my filter was running and water was running out of the backwash pipe!!!
Glad you found the leak! Spider gaskets are a huge pain, and mine never seems to seal perfectly (Hayward 48sqft DE filter). Recommend you put a ball valve on your waste line and leave it closed unless you're backwashing.
Thank you. I just got a plug (pool store recommended) and my husband is going to do it today. I will look up what a ball valve is and maybe do that. This forum is great! Thanks for all the help!! It saved me a lot of time and money trying to get a leak detection company to come out.
