Finally found a head loss curve for my 1 hp pump.
I'd estimate total 1.5" pipe run (skimmer to return) is 20', looks to me like I'm off the chart and I'd estimate I'm at 85 gpm, my pool is +-9400 gallons so I'm getting 1 turn over in just under 2 hours......wow, seems high compared to other peoples numbers. I bought a 1hp pump with the anticipation of adding solar heat on the garage at some point.
I noticed last year that my pool temp was consistently lower than 2 of my neighbours even though they have the same amount of sunlight per day and we all use solar blankets. I was running my pump for a solid 10 hours a day, so that equates to 5-6 turn overs a day...no wonder my water quality was awesome, I'm thinking that all the pumping is cooling the pool down.
I'm thinking about cutting my pump run time down to a couple of hours in the morning and a couple of hours during the evening, 1 turn over each time, any thoughts on that?
I'm hoping the pump run time is still enough to clean the water (obviously I'll monitor with testing) but I'll get some extra heat thru less cooling action.
I'm also thinking my hard plumb job should be 2" pipe.
