Let me apologize in advance if this is posted in the wrong forum. I'm attempting to dial in my pump/filter run time in order to get it to the lowest amount of time possible and still turn the water over once a day. The quandary I have is I don't know for sure what pump I have. As near as I can determine it is a Sta-Rite Dura-Glas P2RA5EL. I don't know this for sure, but working with Pentair and looking at the pump flow curve sheets they sent me for the Max-E-Glas/Dura-Glas pumps I think this is what I have. Using figures posted by mas985 on other threads I "think" I have a system head of about 65 feet which would put this pump at about 50GPM. Is there a way to find my flow for sure that doesn't involve buying expensive gauges or is it going to be one of those best guess type scenarios? Below is the information I used to come up with my numbers...
Pump Make/Model: Sta-Rite Dura-Glas (fairly sure) P2RA5EL (best guess based on fact that it is a 1hp motor with a 1.25 SF
Filter Type and backwash valve model if known: Hayward S244T with a Vari-Flo XL Control Valve
Filter PSI reading at the desired valve settings and pump full speed: New gauge reads 16psi on clean sand when in filter position
Optional: Pump suction reading (in-hg) - not necessary but improves accuracy: Would be more than happy to provide this if someone could tell me how
Pool/Spa valve: No
Suction side plumbing system description: 1 run of 1 1/2" pvc. Pump is about 15 feet from the pool, there are 3 90's and a wide mouth skimmer in the run. Pump is about 2 feet below pool water level.
Return side plumbing system description: 1 run of 1 1/2" pvc. Filter return is about even with eyeball, there are 3 90's, a salt cell (funky compu-pool cell), a 1 1/2 x 3/4 tee to feed a rain effect that is currently capped and a 1 1/2 x 1 1/4 tee for fresh water input and a 1" eye
Any help you guys could provide would be greatly appreciated.
