Measure the pipe OD... if that's an in-person picture. Check this for conversion from OD to nominal sizing. PVC and CPVC Pipes - Schedule 40 & 80
If I had to throw a wild guess, I'd say it's 1.5" PVC.
dw,
I doubt the skimmer pipe size has much to do with your flow switch issue...
When I run at 1,100 RPM, my flow switch is intermittent. So I run at 1,200 with the same basic pump, but then I don't have to push anything through a heater.
My guess is it is more a function of how everything is plumbed.
How about a picture of your equipment pad for reference.

I have. That's not a UPC code.I would have guessed 2" ... have you blown it up and googled the numbers on the pipe?
That was one of the first things that I did. I have about 30 pictures of the piping that I took so I knew where everything was, and I scoured the pictures for some sort of a clue. Seems that about everything on the pipe has to do with its rating and not its size...I would have guessed 2" ... have you blown it up and googled the numbers on the pipe?
I'm guessing that the heater may add some resistance as well. I swapped out the check valve for a FlowVis last week once I got done hooking up all of the automation equipment, and when I did it, I replaced 3 90's (coming out of the heater just before the SWG ) with long sweep 90's and made sure that I had a good run of pipe before the SWG.dw,
Thanks for the pics.. I was looking to see if the same idiot that plumbed my SWCG also did yours, but that does not appear to be the case. I have a 90 right before the SWCG.... Sigh!! That has got to mess with the Flow switch.. It appears you do not have that problem.
I would assume there has to be some extra resistance to the flow when a heater is installed?? Too bad you don't have an external by-pass, because that was going to be my next suggestion.
For reference, when I'm running at 1,200 RPM I get about 2 or 3 lbs of pressure on my filter. What are you getting? Your filter is not dirty is it?
I guess my thought is.. unless you plan to dig everything up, it is what it is...
Sorry I can't be much help with this one,

I'm literally right at 1500 RPM. 1490 won't do it. I burn 186 watts at 1500. I guess I was just expecting that I'd get by with closer to 1000 RPM. At 186 watts vs 100 watts, it's all going to get lost in the overall electrical of the house. It's not going to make much of a difference, I'd just like it to be as efficient as possible. I'm running the pump 24x7 at the moment - not really sure why - I was doing it right away just to aid in filtering out the construction dirt.I also have to run my VS pump at 1400 to reliably trip the flow switch, but that's still only 200 watts. No a big additional cost to run the pump 200 rpm higher for the few hours it takes to generate my chlorine for the day. What, are you concerned about burning an extra 50 watts or so of electric times a couple hours?
