The pump recently started to not push water to the upper waterfall on low speed (1,725 rpm). It has for years not had a problem. The waterfall is about 3ft higher than the pump. I can see that it is pushing water through the pool outlets, just not enough to reach the upper waterfall. Obviously it is sucking water fine.
It was suggested that the impeller may have a leak and is therefore not creating the relevant pressure to allow the water to rise the 3ft necessary.
The pump works fine on high (3,450 rpm) (as far as I can tell) and pushes water to the roof solar heater approx. 15 high.
Any suggestions on what I need to replace?
