Working on a valve right now (replacing seals). Seems like a little lubrication is in order because the new seals seem pretty squeaky and, I would think, hard to scoot intoning place.

Cooking oil?

I didn't tell my wife but I wash the tank valve the the kitchen sink with hot water dawn and then some bleach and now it works really smooth. I just have everything clean and ready to assemble. I just need to know what to apply to the connection before it gets cold again.

outstanding Bill - evidently, you must have been a technical writer, to say the least, in your previous life!

I have never had to replace the whole valve assembly. I just replaced the valve itself. If these are all PVC parts I would guess PVC glue would be the best after cleaning eveything

White parts are made of PVC and black parts are ABS. Home Depot and Lowes both carry a glue that welds PVC, ABS and CPVC.

I have been told the tank is made of polyethylene and regular pvc glue will not stick. They make a glue but I decided this coupling would be as good and I can take it apart should need be.

It's Sunday afternoon so I must be working on the Sabre...

Got new seals last week and proceeded to install today. Thanks for the vaseline tip. Between that and a little dose of olive oil the apparatus opens and closes nicely. It also seems to hold just fine.

However, the seal between the valve and the flange on the tank has a tiny drip. After pulling it all back off again I notice a small amount of damage to the flange surface. Looks like some previous repair effort may have had a tool slip or something and marred the surface slightly in one spot. I also notice when I first took it all apart the first time that the last repair effort by a previous owner included a big dose of silicone applied to same surface prior to final assembly. Probably what caused the seals to fail the last time.

Anyway, any suggestions as to how to address this latest issue? I suppose I could try the silicone trick again only with more precision so as to avoid it spreading too far and contacting the seals. Risky... Other thoughts?

As a newbie I ask, is any drip no matter how small a total breach of etiquette?

It's funny how ideas come to you when you need them. As I was putting the valve in today it happened. One bolt is very difficult to reach. I could touch it with my third finger as it protruded through the assembly but there was no way to hold the nut while reaching that far. What to do? Inspiration struck. I had been wearing disposable rubber gloves which were mostly useless as they tore so easily. So, I punched a 1/4" hole in the tip of the third finger where my finger print would be. Cut another hole further up, dropped the nut into the glove and maneuvered it down to the tip until the hole in the glove matched the hole in the nut. I was then able to reach into the space and hold the nut in place while tightening the bolt. My tip for the day.

That rubber fitting works great. I filled my black water tank full of water and it holds great.

great idea!

The saga continues...

I cut a piece of inner tube and created a gasket to try and address the scuff marks on the flange. Seemed work OK. Everything held fine for 5 minutes. Then a trickle of water started but it wasn't coming from the area of the new gasket.

Apparently, there is a leak somewhere above. Likely between the flange and the tank itself. I gather that the pipe and flange are an integral part of the tank. Created as one or can they be taken apart? That is my new question. I'm not real keen on doing what it would take to put a whole new tank in place just now.
