Hello all,
When I turn my controller from pool to spa, the valves turn, the heater starts up and water slowly comes from the hot tub jets. The pressure of the water coming out is very low and I can not hear the normal bubbling from the vent I used to hear on startup. The remedy is to blow air into the vent pipe, we use a leaf blower, for a couple seconds and then the normal jet pressure will start and you can hear the vent start bubbling. It also appears that the amount of time spent blowing air into the vent is increasing in order to clear the line.
Any ideas on where to start? Nothing seems to be operating any differently than it had previously before this started.
BTW the valve setup in the pic is for normal pool usage but the valves move appropriately when called to.
Thanks
