    Plumbing in autopilot question

    So I got my autopilot yesterday and plan to plumb tonight. The manifold is built well and thus has some weight to it. I am concerned about this weight "sagging" my pipe and stressing the glue joints over time. Should I elbow down and plumb on the floor and add friction loss? or Should I keep it in line about 8-10" off the floor? I am using 2", sch 40. Any pics?

    p.s. I am plumbing and capping a in/out for future heater-How much room between the tees is necessary to make life easier later?

    Unless you have a very long run of pipe (as in 10') I wouldn't worry about the cell sagging it. Especially since your using 2" sch 40.

    I like to leave at very least enough room between fittings that I could add a tee between fittings if I had to. About 12" between fittings is my preference but sometimes space dictates smaller. I very rarely butt them right together. There's only one place on my pool that two fittings are butted together and I made that decision during installation to prevent a trip hazard.

    Shouldn't cause any issues that I could see. The manifold weighs about 10 lbs.

    Let us know how your install goes and give me a call if you have any questions.

    Re: Plumbing in autopilot question

    So I have been reading that the flow switch on the SWG shouldn't be my only safety for operation without flow. I have my Ecostar VS pump wired already and it has its own timer built in. Since I am not using a dedicated timer, how would I go about tying the pump power to the autopilot swg? I don't want an explosion in the new poolhouse!

    The best thing to do is to use a current sensing relay to turn the SWG off unless the pump is drawing power.

    Where would the relay be? On the swg or pump? I have no automation. I wonder if i could use the pump start relay in my irrigation controller? It is designed to kick on a booster pump when the timer sends voltage to a valve solenoid.

    There are a couple of examples of current sensing relay installs here.

    The relay senses the current flowing to the pump and switches the power flowing to the SWG.
