I have a leak that I can't figure out.
Spa water level dropping at around 2" in 24 hrs.
Size of spa is approx. 8 ft. dia. and 4 ft. deep.
Pump is off and multi-port valve is in "filter" position.
I have replaced the spider gasket but didn't help...... much, as the problem isn't completely solved.
Before I replaced it, I could place my ear against the pipe leading to the heater and hear the water "flowing", "trickling", or something like that.
oh I also replaced the check valve too.
I did a little test, marking the level of the pool and the level of the spa.
the spa dropped in level but the pool did not so something is wrong in the spa.
