    Looking to install a SWG. How straight forward will the plumbing be?

    I currently have a pretty straight forward plumbing system. 2" piping, being sized to 1.5" to enter/exit equipment. The easiest place to put the SWG would be the diagonal pipe in the foreground. Are SWG's required to be installed in a certain orientation? How about the flow switch and a proper amount of straight piping before it?

    I'm also looking at upgrading the single speed Superpump to a variable speed pump. I am considering a A.O. Smith ECM27CU dry end replacement, but if the plumbing for the SWG is going to be involved, there is really no reason to only replace half the pump at similar prices.

    If the flow switch is before the cell you need a minimum 12 inches of straight pipe before a 90 (elbow). If you install the flow switch after the cell, you can add the cell in your measurement meeting the 12 inch minimum guideline. You would install the SWG on the outgoing run from the filter. If you had a heater, the swg would be installed after the heater.

    Although very close to each other, the plumbing work for the SWG and the plumbing work for replacing the pump have no overlap, and be done/or not do completely separately from each other.

    Most brands of SWG will be fine on the sloped pipe, but a few brands require horizontal mounting.

    I am considering the "Circupool SI 45" or the "Hayward Aqua Rite 40K". Do you know the requirements of either of these units?

    Circupool says "ideal installation is horizontal", which is a little ambiguous. AquaRite is fine in any orientation.

    I just looked at my setup again. Am I going to be in trouble if the intake to the booster pump is after the SWG? Will the increased chlorine significantly hurt that pump?

    Mine is plumbed that way and has been running that way for 8 years.

    I have a circupool arriving next week. I guess I get to go solar salt shopping now.

    I own a Circupool SI-30 +, according to my manual the cell can be installed either horizontal or vertical so, diagonal should be no problem. +1 what Donny said, the flow switch must be installed at least 12" after any elbows. Installing it after the cell will make sure you meet that requirement. However, they stress that the cell & flow switch must be installed after all other equipment. Installing a booster pump after your cell could cause cell or switch problems.

    Re: Looking to install a SWG. How straight forward will the plumbing be?

    Aaahhh... just got my si-45 delivered. I was told that the cell was about 12" long. But after assembling the cell and the unions, it totalled 16".... 1" more than the 15" of pipe I have to work with. I'm now trying to figure out the easiest way to gain 1+" and not add too much extra plumbing resistance.

    Cut off the straight pipe below the lower 45* angle and to the right of the upper 90* and replumb at more of an angle.

    Or get rid of the angled pipe and just go up vertically all the way to the top and use a 90 over toward the filter pipe.

    Either way you are going to have to redo all the pipe coming out of the filter.

    Re: Looking to install a SWG. How straight forward will the plumbing be?

    I thought of doing it both those ways. I was even wondering if it would be beneficial to re-orientate the multivalve, but that would be significant work. Since "horizontal orientation is ideal" according tto the manufacturer, I might go with the increase the diagonal approach. Also, the return pipe entering the ground is a bit crooked away from the pad. The vertical mount might draw more attention to this defect. I think it's time to buy PVC, joints, primer, glue, and of course loads of salt.

    Wait a minute, how are you going to make the diagonal longer? The fittings are 45, so you can not change the angle.

    Re: Looking to install a SWG. How straight forward will the plumbing be?

    I think the idea is to droping the 45 on the vertical lower, then extending the short pipe above the 90 and tweaking the directions of all three of the angles on the return to get it all to line up.

    Yes, shorten the straight pipe between the T and the 45 and then tweak the angles of the two 45s and the 90.

    Re: Looking to install a SWG. How straight forward will the plumbing be?

    Well it's done. Went the vertical route, but used 1x 90 and 1x 45 to make the connection. When it came to dry fitting, I just wasn't comfortable trying to preserve the diagonal.
