Been a while. But every new season (Southern Ontario Canada) I come by and catch up on some reading. So much here, all the time. In know many forums frown on asking q's that have already been dealt with, but with soooo much detail and information on this site, it is hard to know if you read it all and where to quickly find answers. Well for me anyways. So, if there are threads I missed on this, please direct me to them.
I replaced my Hayward 1HP Super Pump last week. She was getting really loud and hot! Bought a 1.5HP Pentair Superflo VS (Mod 342001).
Now I have lots of experimenting to do with RPM's and determining best flows for filtering, skimming, heating and simply movement (avoiding stagnant water).
I was wondering what suggestions and input members would have.
Firstly, the manual is vague on a few things.
Does anyone know how I can get an estimate on flow (gpm) based on what rpm the motor is set to? My plumbing is 1.5". I want to be able to determine time and speed for turning over the pool water.
The manual and the lid to the pump basket both refer to releasing pressure when opening the compartment for cleaning the basket or to bleed air when priming. However, I can not see any pressure release. Anyone have this pump who can explain what to do during priming and when opening basket compartment?
So far I have determined my heater fires up (and stays on) at 1050 rpm.
950 rpm not enough to fire heater and no movement in skimmer, but prevent the water from being stagnant. A few air bubbles appear in the pump basket compartment
1100 rpm creates steady rippling at the jets enough to get skimming working with a nice lazy spinning of the surface water in the skimmer basket. Water is hot to the touch at the jets
1500 rpm is a nice level of ripples at the jets and suction at the skimmer to keep surface nice and clear. I get lots of tree pollen, bugs, and stuff floating so I like surface to keep clear. Water is bath warm at the jets.
2500 rpm seems to be about as strong as the single speed Hayward Super Pump and I can get a decent vacuum job done.
I was told by the pool store the heater needs to cool down with enough water flow before dropping to a slow speed for simple movement. They had overnight set to 2500rpm for filtering and around 7am dropped to 1500rpm to cool heater and then an hour later drop to 950rpm for the rest of the day and when electricity is at peak costs (Ontario has time of day rates where more $ during day than night and weekends). They did not realize my heater still fires at 1500. So if the heater happens to be on at 1500 and then rpm drops to 950, should I be worried about not enough water flowing through the heater if it shuts down?
Any input to all or any of these matters is greatly appreciated!
