    Sticky Multiport

    Hi All

    After a recent backwash, my multiport handle is somewhat sticky. I push the handle and rotate it to the function I want, but it will not raise back up to the proper position... causing water to run out of the waste line. I have a ball valve on my waste so I can continue to circulate, but does anyone know what I can use to lubricate the spring mechanism on the multiport?

    I'd suspect it's more than just the handle. There is an O-ring that seals the top, and that may be the source of the problem. If you pull the top off the MP, you can lube the center shaft.

    Thanks John. What kind of lubricant would you suggest?

    My MP selector failed because the SPRING rotted away.... I believe you have to pull the MP apart to visually inspect the spring on the top half. There is a spring that forces the sections to close-off, BW, Cir, etc without that spring the handle will be limp and while you can spin the handle set the preferred setting with the handle, inside the spyder gasket isn't able to seal without the pressure from the spring. For me this meant the spider gasket slid-out of place and took on a new unusable shape. I had to get a rebuild kit less than $20 that includes the spring and some washers and then a new spider gasket. I was back in-shape in no time... Good Luck!!!

    Thanks wanna-be. The spring appears fine, but sticky. Good to know about the rebuild kit; I may need to take it on if I can't just lubricate this...

    I'd just use pool lube. It won't hurt the O-ring.

    check the non-metallic bearing(white washer) under the handle for wear, replace or flip over if needed, also lube the bottom of the handle or replace it because of wear
