I just had a pool build finished last month by a reputable builder and overall it has been one issue after another. One issue I have been fighting is how loud the tristar vsp pump is at the speed needed for my in-floor cleaning system.
I had a rep from A&A come out and check on the infloor system and one of the things he did was check the pressure at the popups. To get the flow they recommend he has my pump now set at 3278rpm during the infloor cleaning cycle, 4 hours. The pump is 20' from my house and I have a large home, and I could hear the thing from anywhere inside my home. When outside, it was louder than my A/C units... it drove me nuts and I am sure my neighbors too. So I started looking into the sound and they initially installed the "concrete pad" (which is actually foam with a thin concrete shell over it) over my decorative rock and that lead to some bad vibrations which I made them fix and also had them put a vibration isolation pad between the pump and the concrete pad. There is no longer any vibration on the pad. The housing over the fan was making a bad noise, I loosened it and aligned it better and re tightened it. The pump does not appear to have anything mechanically wrong or cavitating. It is definitely quieter but I can still hear it in parts of my house and it is very loud outside... much louder than I care to live with. I was actually under the assumption I was getting a ecostar from the pool builder and not the tristar as that is what we discussed, but looking back they charged me for the tristar and installed that so here we are...
My thought is, that if I had a higher HP pump I could run it at lower RPM and it would cut down quite a bit on the noise. I am basing this on how much quieter my pump is at 2500-2700 vs 3200(not just the motor but the fan)
I put a vacuum gauge and pressure gauge to calculate my TDH and find my flow rate. At 3450 rpm- 5.5 in hg and 26psi for a TDH of 66 with a flow of around 65gpm. If I am operating at 3278/3450 then the flow supposedly required by my infloor is around 61gpm.
I know TDH changes based on the velocity of the water, so I am a bit lost in how to find out what RPM I could run the ecostar at to get the same flow. Can anyone help me get an estimate of what I could run the ecostar or how the noise would compare between the two pumps? I would be really happy with the noise level of my tristar at 2500 or 2700rpm. Money and efficiency is not a consideration here, just noise levels.
I am getting good skimming still at 1500rpm so that is what I am using for my low setting.
If you made it this far, thanks for reading the novel...
