I have a recently started-up 8k gal pool/spa - there is a single intelliflo vs pump, dual main drains in both the pool and spa, and two skimmers. The spa has 6 jets for 'spa mode' and 2 returns for pushing water over the spillway in 'pool mode'. There are two air-blowers plumbed into the jets and four metal air grids in the spa floor. The jets have a fitting in them that is a rotating dual-orifice plate. The pressure when in spa mode (all water coming through the 6 jets, all suction through the spa drains) is pretty weak. The spa model runs the pump suction through all the equipment (filter, heater, heat-pump, uv light) before returning to the spa (it does skip the chlorinator). The pump is set to highest speed in spa mode.
My thought is the weak jets are the result of either:
1. The wrong (for my amount of pressure) fittings on the jets
2. Not having a bypass on the spa suction to go from spa drains to pump to heater and then straight back to spa jets without passing thru filter, heat pump, uv,.
I can't imagine that this pump isn't big enough for 6 jets in my not very big pool.
The equipment is about 25ft from the Spa, 2" pipes.
Any suggestions? Obviously I am going to discuss with PB but wanted to get prepared on what to ask for.
