Plumbing design

[jeflogan]

Newbie here disregard the pool depth it will be a sports bottom I used an image from pool warehouse. Am i crazy not to combine the lines closer to the pool? Any advice is appreciated.

'Home runs' are nice to have. A must on the skimmers/suction.

The returns are good to have as individual lines. If you have an issue with one, you can turn it off and still have the others.

If you combine them, then they should be looped so the flow to each of them is relatively the same.

Do those skimmers take advantage of the prevailing wind direction in your yard? Just something to think of.....

Looping together all returns on one line and skimmer/main drain on another line is the way pool plumbing was done for many years. Lots of us have only one return line and one suction line by the pool pad. If you have a simple pool it should work fine.

Having individual home runs gives you more control to balance flows if you have valves in them. And makes it easier finding plumbing leaks. So there are pros and cons to each approach.

Here is my pad plumbing design i flip flopped the pump and heater. V' are valves. Does this look like it should work? I guess I don't need the 2nd valve in the heater bypass, do I?

I like that each line in/out has its own valve, but not sure you need those directly behind them? And I would ditch the second one after the heat pump as you're correct, it seems redundant.

If you remove the 2nd valve on the heater bypass you need a check valve between the heater and T on the SWCG side. Not for the SWCG, but to keep the pressure off the heat pump. They have a pressure switch and it could be activated with out a check valve.

 

[YippeeSkippy]

The check valve would go in the spot that he has marked for the valve, right?

 

[mknauss]

Actually on the right side of the T that would replace the valve.

Thanks Maddie, I did not see the redundancy of the 3 way valves. I will replace the 3 way with a check valve Marty.

Thanks again, you have been a big help.
Updated drawing.

What do you intend to use the hose discharge for? Are you going to have a main drain? You can't drain much from skimmers.

I am not a cartridge filter guy but if you can put a Multi Purpose Valve on I say to do it. A MPV gives you RECIRCULATE and DRAIN TO WASTE settings. We see folks who get an algae problem and their filter keeps on clogging and they don't have a RECIRCULATE setting to let them do the SLAM while bypassing the filter.

Our city code requires a connection to the sanitary sewer for salt water pools. No main drain I will have a vacuum port lower than the skimmers so I can drain through that.

What will you do if you need to drain below the vacuum port?

As Arnold would say Pump It Out!!! Our deep end is only 31 sq feet and did not want to feel the main drains on my feet and it is too late to think about adding main drains anyway.

With a month of rain and the poolcrete being finished today I can finally get to plumbing. Question on flow and to make sure that each line receives the same amount of water pressure. I have 6 lines (3 suction and 3 return) and plan on plumbing each side as below. Will my flow be similar with each line if I plumb this way 2-90deg and 1 cross fitting? Please share if there is a better way.
