    Why the multiport valve hate?

    I recently had my pump and filter replaced. I did not want to do the installation myself so I contacted four different places to give me a quote. Once of my requirements was a multiport valve that allowed vacuuming straight to waste. Three of the four contractors expressed various levels of disdain for multiport valves, citing supposed unreliability and/or difficulty to maintain. One even refused to sell or install one. I went with Leslie's of all places, because not only were they slightly cheaper than the next cheapest, they were the only place that didn't ***** and moan about the prospect of selling me a multiport valve.

    The tap water here is loaded with particulate which gets released as a nasty yellow sludge as soon as the Ph is lowered and I also get a bit of wind blown dirt on the pool from time to time. With my previous equipment I was having to backwash almost weekly after vacuuming the bottom of the pool. Being able to vaccum to waste has been a godsend. I previously had one of those pull valves that you pull up and down, which gave me nothing but trouble during the two years I used it.

    I don't understand the hate on mutiport valves. If it hing lasts only one year it would be worth it to me over that horrible pull valve I had before. I'll just buy a new on and install it myself, as they are around $100 online.

    Is this hatred for mutiport valves among contractors common? Is it justified?

    So far, I love the thing!

    Never heard of the hate ... other than from someone on here hating the push-pull as far a maintenance.

    There is really nothing to go wrong on the mulit-port other than a spider gasket every once and awhile and they sure are more convenient in a lot of cases.

    I too wonder why you got the reaction you did.

    Over the years quite a few people have said that they prefer multi-port valves. The only advantage to a push pull valve I can think of is that it costs a little less.

    I believe you get a better, less restricted flow via the push pull valves but for convenience multiports are much handy er

    Hmmm. Probably just a coincidence that I ran into multiple members of the multiport valve haters consortium. It's a sparsely populated rural area, so maybe they all know each other and have formed a consensus opinion.
