I have an above ground pool, we didn't shut it down for the winter and we had a hard winter when it would freeze we would turn the pump on. Now that it is in the 70's I have added chlorine we had to replace the pressure gauge because guess the other one froze and stopped working and when we changed the gauge it still only read about 8-10 psi. Also we took the pump apart to check to see if we had anything clogged and we didn't, we also replaced the filter sand.
THe pool will be only 2 years old this august. When I was out there brushing the pool I noticed water coming from the waste port where you back wash and the pressure was barely registering. So I have turned the pump off because I don't know what to do next.. But since it is getting warmer I don't want to leave it off because I don't want the green monster to appear. Anyone have any suggestions or advice
