Here's a question for those of you with experience with a pool
multi-port valve. I've been having a debate with a friend who
says you're only supposed to turn them in one direction otherwise
it will screw up the spider gasket that's at the bottom of the
valve. But I don't see how that can happen. The valve uses a
spring to push the disc inside down onto that spider gasket/seal.
To move the valve, you push the handle down, which moves the disk
up so you can rotate it. At that point, nothing is even touching
the gasket/seal, so I don't see how which direction you turn it
matters. I do see how if you try to turn it without pressing
the handle all the way down, that would rub against the gasket
and could dislodge it, screw it up, etc.

I've also seen threads about this online, with some alleged pool
experts also giving the "only turn it one way" advice. But the
manual for the valve says nothing. Nor is there any arrow or
indication of this issue on the valve itself.

Here's it the type of valve:

I've not had that type valve. Seems to me it would be okay to turn in
either direction. I mean why turn from backwash to close by turning
all the way around (left) in one direction when you can change to
close with a simple move to the right?

The theory from the believers is that the spider gasket at the
bottom doesn't like getting rubbed both ways..... But like I said,
when you push the handle down, it lifts the plate gizmo completely
off the seal, by probably 1/4" so I don't see how it can happen.

Here's a diagram of the valve:

http://www.poolcenter.com/images/PC_...ts_SP_0598.jpg

The gasket/seal is #11, the plate that presses down on it is #10.
The plate has a spring that pushes it against the seal. When you
push the handle down to move it, it pulls the plate up off the
seal, compressing the spring.

SWAG is the "believers" have read to much into the operation of the
valve. If it was intended to operate in one direction - there would
some type of stop to prevent both directions, no? If 10 is clearing
11, it can't rub, best I can tell.

I have a problem? I posted a legitimate question here. YOU
came in here, didn't post anything to do with the question
and instead started a personal attack. That's because
you obviously don't know anything about pool valves or anything
else. As for the Micky thing, no tirade, just asked for a link
to his ridge vent product that has the impossible characteristics
he listed, that's all. You're just sore because whenever anyone
ask you to back up anything here, you can't and you wind up

As I stated in my original post, nothing in the manufacturer's

you think a pimple faced summer HS student is an expert.
Thanks for the usual, what does the MF say stuff. And I gather,
like some others here, you don't even know WTG this valve is,]

Again, you don't know the subject material, so why make an ass
of yourself? I know. That's what you libs like to do.

The only time you do not want to turn a multiport pool valve
in either direction is when the PUMP IS ON.

I made that mistake 4 years ago, replaced the whole
Hayward head, and never repeated it.

Other than that, it's just like a TV tuner knob - can
be turned either way.

I manually turn Jandy valves all the time while the pump is on. I can
purge air from the skimmer line or the cleaner side port line in the
pool. One Jandy has a actuator that turns on the solar panels when
temps fall below the settings.

The instruction manual for the Haywards,

from moving the valve selector while the

Why do you start name calling. All I said was I turn Jandy valves on
while the pump is running - manually and with an actuator.. Maybe you
can explain your Hayward valve and give a model number? Or would you
like to continue calling people idiots. I can call people names with

I admit that it doesn't seem to matter but it may have something to do
with not pushing the handle all the way down when twisting. I replaced
mine Nov 2013 and I'm not having any spider gasket issues. As I recall
there is a ridge that can get worn fairly easily. You can see the ridge here

I replaced the spider seal here about 2 years ago, I think.
This time it's the shaft seal that has a slow leak. When
the pump shuts off, you can hear air going in and over hours,
the filter tank winds up draining back into the pool. I have
a seal kit coming.

I agree that not pushing the handle all the way down could
be a problem. Some of those gaskets apparently aren't even
glued in. If the plate is still against it, not only would
it wear it, but could also pull it out of the gap it sits in.

Jandy is a different design - more like a ball valve (using a cylinder instead of a ball) and meant to function under pressure. It seals radially unlike the multi-ports which seal axially via the spider/wagon wheel gasket.

The only time you do not want to turn a multiport pool valve
in either direction is when the PUMP IS ON.


I manually turn Jandy valves all the time while the pump is on. I can
purge air from the skimmer line or the cleaner side port line in the
pool. One Jandy has a actuator that turns on the solar panels when
temps fall below the settings.

I made that mistake 4 years ago, replaced the whole
Hayward head, and never repeated it.


hmm?

Other than that, it's just like a TV tuner knob - can
be turned either way.

Jandy is a different design - more like a ball valve (using a cylinder instead of a ball) and meant to function under pressure. It seals radially unlike the multi-ports which seal axially via the spider/wagon wheel gasket.

Jandy multi port valves have a "defuser" sp?, turned one way it
shuts water flow off for that line. Same when turned the other
direction. It isn't a "ball valve".

Sample; #9 is the defuser.

Ball valves work differently.

PRIVATE PYLE, YOU JUST LIKE TO BE
DIFFERENT!!!

The instruction manual for the Haywards,
at least, says that DAMAGE CAN RESULT
from moving the valve selector while the
pump is ON, under pressure of water passing
through it.

Why do IDIOTS always have to challenge and
refute everything I say on Usenet??

The term "full metal jacket" refers to a bullet's casing. It has nothing to do with the guy's jacket. (lol)
