Yes, the builder knew about the debris as he took the nozzles out of the jet body himself prior to me doing so and admittedly removed a lot of rocks before I did the same again. I have now had them on and off several times since to check and there is no longer any in the nozzles themselves. I was worried that there may still be debris prior to the jet body somewhere as they were definitely sloppy in their work. To give you a bit more info/history prior to purchasing the 2hp pump: When the builder completed the job we got in the spa when we were able to get our water prepared properly. We immediately noticed very poor pressure in all 10 jets and couldn't achieve any sort of hydrotherapy without using the air blower. Some of the jets were barely even moving water at all. After notifying him of this problem he came and tried to figure out the problem. He gave me all sorts of excuses that didn't make a lot of sense to me and then told me that he originally planned/plumbed our job for 3 pumps (3 smaller pumps), and had decided to buy only 2 (both Intelliflo 3hp) instead. He used some 3-way valves in order to change from 3 pumps down to 2. He proceeded to turn one of the valves and asked me to check the pressure out of them after he did this. The pressure was excellent when in either position (5 jets only, or 5 + circulation). Once he put it back to full open position with all 10 jets there was again a huge drop in pressure. This test was done using only a single 3hp Intelliflo. He mentioned to me at that time that in order to get that kind of pressure that was felt with 1/2 jets closed I would need to purchase an additional pump. This was when we purchased the 2hp Whisperflo. When this additional pump was installed I was immediately disappointed in the outcome as there was very little change at all in pressure on the 3hp Intelliflo side even with 5 of the jets now put on a separate pump! I also noticed that the pump sounded like it was unable to prime and stayed at full RPM making a lot of noise. I looked into the filter basket and noticed that it was only 1/2 full of water and the suction side of the pump was unable to keep up. He then told me that the suction was unable to keep up and that I couldn't run my 3hp pump at full rpm. I was very angry as what was the point of having 3hp if I could only now run 1 1/2 to 2hp??? I didn't accept that answer and then he finally admitted that there was a blockage somewhere in the suction line. After plumbing the 2hp pump to back flow the drain/circulation lines 2 plastic grocery bags came out of the floor drain along with a golf ball size chunk of plaster! At this time the builder stated that he thought there might have been a blockage prior to me getting him to admit this and that he tried to use the bags to push it out? Obviously, at this point I knew he wasn't being totally honest with us and that he was probably pretty careless. I proceeded to get a second chunk of plaster out that was the same size. Magically, the circulation pump could now prime and keep up with the full rpm's. Once again, the pressure in the jets did not really change a whole lot.
It is a fairly straight shot to the equipment from the spa. (backyard spa with equipment just around the corner of the back of the house)
the elevation from the equipment to the spa is approx 3-5' maximum
Just a couple of small marble-size air bubbles in the top of the pump filter basket area
Not sure of diameter of nozzle but I will measure tomorrow and let you know first thing in the morning
Thanks again guys for your time and help with troubleshooting this problem
Anyway, I don't recall any name or anything like that on it but I could find out if it would help.
