I bought my pump & filter as a combo, and even though it is 1.5hp, it seems to only be rated as 54gpm. Seems low. Given that I have the equipment installed about 20 feet from the pool, with 1.5" pipes, I figured I better find out what kind of flow I was actually seeing. It matters to my heater, for one.
So I bought a flow meter, and hooked it up today. On high speed, I see 35gpm. Low speed, 15gpm. I have been ... <cough> ... running on low speed with the heater. According to Raypak, it should be 20gpm minimum. Whoops! Didn't throw any errors, outlet temperature was a nice 12* rise over inlet, but still, it is below spec. And, assuming the pool is 10500 gallons, at 15gpm it takes most of 12 hours to turn over the entire pool.
So I got to looking around, and it -seems- like there is possibly a fair amount of improvement to be had in changing out some of my choices for fittings. Being a bit lazy, I used 90s for most everything. Standard, short radius 90s. Switching to a pair of 45s, or even better a long sweep 90, would that make a noteworthy difference, you think? If I can plausibly raise the low speed GPM up to 20 or even higher, I'll tackle the plumbing work to make it happen.
Since y'all like pictures (I'm with you, I do too!) here you go. Go easy on my wiring, today I'm reworking my bonding wires and they're a bit of a mess until I tidy it up. Also trying to figure out why I can't get my sand filter back down to 13 psi and why it leaks from the discharge port even though it's only a couple months old. Building a pool is fun!
