Pool pump/filter recommend please

No, I'm not trying to push his information aside. I very much appreciate it. I agree that getting a downsized pump and running it on high most of the time is a rational plan.

The problem I see is that going too small won't allow me to get a decent turn-over rate.

I've been doing a little more research and it does appear that I can push a bit more flow that 42 GPH even though its not the best idea. Something on the order of 55 GPH or so.

The thought of using the booter line as a second suction line is very intriguing. That would be terrific if I can do it.

The port on the side of the pool is maybe 18 inches below the surface. Would this really work? BTW: The only reason I call this the booster/cleaner line is that what the previous owner called it and there is an unused booster pump in the pool house. He said he threw his cleaner away because it didn't work.

Can I have 2 1.5 inch suction lines and a single 1.5 inch return?

ALso, thanks everyone for helping me through this.

Hi, Mike,

I would envision the suction side plumbing something like this...two 1.5 lines, contolled each by a ball valve, coming from the skimmers and the booster line, teeing into a 2"line at least 12" long that goes into your pump. Even if you have to come back down to a 1.5 entrance into your pump, that 2' tee will reduce some turbulence and, therefore, TDH.

The downside is that you would have an open suction line on the side of your pool that could grab somebody and could actually be a little dangerous if, for some reason, you shut off the skimmer suction line. You can buy a little plastic guard to screw into that booster line which will greatly help, but not eliminate, that issue.

If you really wanted to get complex, you could tee off that booster line with some more plumbing so it could be controlled as a suction side or pressure side line. I doubt that's a great idea, but it could be done if you needed to.

Mike, if you can get 50gpm through there, that's 24,000 in a 8 hour period which I think gets you right about where you want to be. Others smarter than me may nix this whole idea but it seems to me it would work nicely.

I was thinking a standard Jandy 3-way valve that I would just use as a blend valve. Common plastic ball valves don't seem to last too well.

Also, I do plan to use 2" line on the equipment pad between all components. I'll use bushing as the pipes come out of the ground to get to 2". I will have about 2 ft to the pump entrance, so thats not a problem.

The biggest mechanical problem I see with attaching the two lines together is that they are not in nice positions for connecting together. Trying to minimize elbows will be a challenge.

I'd like some help from the experts too as I'm also looking to go with a two-speed pump.

16x32 foot in-ground w/ vinyl liner. 19,200 gallons before we put steps in the corner last summer.

All 2" pipe.

24" SplashPak Sand filter

2 suctions (only one running at a time) - 1 is 17' (skimmer) run and the other is 27' (vacuum). I believe each has 3 elbows before the 2 near the pump.

1 return is 24' with 4 elbows.

Thanks in advance!! Ken

Mike, will that valve allow you to have all the ports wide open simultaneously? I don't have any Jandy's..I know they're good quality...but I was thinking a 3-way was an "either-or" valve but not both wide open.

Anyway, I think you're on the right track. An extra 90 turn or so won't add much head and you're really gonna' cut it (head) back if you can get two suction lines going. Let us know how you end up.

Hi, Ken,

You'll get much more attention if you start a new thread. Much easier for folks to find and subscribe to.

I did a little more research and, while I found almost nothing about suction lines that are not drains or skimmers, apparently these types of lines are also used as dedicated vacuum lines. The thing is, that you are supposed to have special ports that close when a vacuum is not in use. I assume that is so you done suck up your nephew (or at least give him a big raspberry). I did not find any special covers to add safety. Withoutthat level of safety, I feel I cannot use that line as a suction. We run a day-care out of the house and thats too much liability unless a suitable cover exists.

[duraleigh]

Hi, Mike,

Yeah, those nephews are a pain in the patoot!!! I do have a couple that could use a good raspberry, however!

I would not use that line with a day-care situation, either. The fitting I have seen is a small, plastic screw-in that would not offer adequate protection if, somehow, that opening became your only suction side water source.

(That's how John Edwards won his first big case and, eventually, started his political career)

A cover could be made perhaps, but with your liability exposure, I'd resign myself to the smaller pump. You'll have to run it a little more, but I think you'll still get satisfactory results.

Could you use something like item 34-215 on this page:

Also, the 3-way Jandy valves do have the ability to position such that both lines are on.

Probably can't use that. It would have to fit a vinyl lined pool in a retro-fit application. That looks like it will only fit a new installation since its a solvent welded application.

The question on the Jandy is not that it would open both ports, but would it open both ports fully and create no significant restriction. Two ball valves would create essentially no restriction, but its two parts and the valves are not as reliable from what I've read.
