Tagelus diverter / spider gasket

[Poconos]

Rob,
Strange. First on the gasket, if the manufacturer says lube it, I guess do it. I still have never seen any reference to doing that but I don't know everything. If I read your post right it looks like the water in the turned up waste hose reaches the level of the pool water. Is this with the pump running? If the pump is off I would understand the levels. Pump on, the water in the waste line is at some pressure so I think it would be a lot higher than the pool water level. However, should not be. The waste port should be closed. The only time that port should be connected to anything is in the backwash, waste, and rinse positions. Something still isn't right with that valve. Only thing I can suggest is open it up and look again.

Poconos - I REALLY appreciate your input! I'm with you. You're reading my post correctly. Something is messed up. I do know that with the pump running, the water in the waste hose does go to what, I think, is the pool level. If I leave the multi-port set to "rinse" with the pump off it might as well be called "drain the pool".

I'm actually out of town right now, but I have taken the thing apart a few times, poked around and can't find anything wrong. What this means is that I'm missing something. All I can think of is that I need a new multi-port. I'll be back home on the weekend & will go back at it then, but I'm totally mystified.

It is nice to know that I'm on the right track...

In the rinse mode you would have a siphon going. Skimmer to pump to filter to waste line.
In the filter position that waste line should be totally blocked. Put it in that position and with the pump off try blowing into the waste line and see if you can move air. If you can then something is leaking which I suspect. Sounds like you can take that valve off easily so you may take it off and blow in the various ports to help isolate the problem. In filter mode, waste port blocked. Rinse, backwash, and waste positions, outlet to return line blocked. If you had it plumbed wrong you would have major problems, not these subtle things. This problem will be solved eventually. Keep at it.

I agree with all you've said Poconos. As I remember, a few years back a local pool company was trying to figure out a problem we had & they "couldn't". I think they were pressure testing the lines & their readings weren't making sense. I know that a skimmer was "moved" long before we bought the house. The former owner and former pool company were useless. short of ripping up the yard, I'm think I'm stuck w/ the way it is, at least until the filter dies, or we get an underground leak (knock wood - I hope that's decades from now). Thanks for confirming what I've always suspected : our pool was plumbed by Mario & Luigi... the Mario Bros.

Rob -- I just had to tell you --- I am the one who moderated your post in after you posted and when I read it, your last comment made me laugh! Thanks for the chuckle. That was great!

Glad that it got the desired effect. Gotta have a sense of humor...

Just as an FYI - I just backwashed my filter and left the pump off, but w/ the multi-port set to "filter". My backwash hose fills up to the return pipe level. I never did get around to blowing into it, but now I think I don't have to. Seems like a bad multi-port to me. Guess I'll be replacing that sometime.... Right now it's not causing me enough grief to spend the time & effort.
