Hi,
Our tub has two pumps, both are working, but some of the jets are not functionning.
Pump 1 is working fine.
Pump 2, which includes the volcano floor jet is not working properly. It should have two speeds, but only works on full throttle and more - we have a fountain in our hot tub! Not all jets have water/air coming out of them. We have turned the valve that switches the jets to the volcano pump and no change.
We regularly empty and refill out tub and always drain the air out of the valves.
Thanks.
