Fleck 7000 / Clack Resin Tank Leak - Plumber Installation Problem or Defect

[ditttohead]

I was referring to post 30.

As to lubricants... most all NBR, Butyl and other "rubber" O-rings should be lubed, silicone seals are water lubricated. Clacks intenal piston contact seals are silicone which do not use a lubricant, all other o-rings in the Clack valves can and should use lubricant. The right lubricant is critical, see the attached product bulletin from 2006. http://www.pentairwatertreatment.co...nt/Bulletins/529-Lubricants on Components.pdf , and again from 2001 http://www.pentairwatertreatment.co... Water Treatment/Bulletins/376-Lubricants.pdf

And as said previously, the lube can be water but all manufacturers use silicone lube when valves are assembled at the factory.

So many replies to the whole lube issue I was beginning to think I had logged on to the wrong site LOL

So nobody is surprised that I couldn't manage to destroy either a valve or a tank by grossly cranking on them?

I'm just about ready to start testing the whole mis-alignment thing too. I really expect the bypass to break the fitting on the valve head if anything at all but I wouldn't be surprised if I wind up hanging the whole tank on the assembly with no leaks or breakage at all. At least for a little while. Over time I have no doubt that something will give.

The biggest problem we have seen with tank neck cracks and valve failures is the lack of flexibility in the pipe. The tanks expand and contract significantly as the pressure rises and drops. Hard plumbing without any accommodation for this can lead to failures in time. All commercial equipment requires it. "NOTE: Flexible connections must be installed between hard piping and tank openings. Failure to install fl ex connection properly with the vessel will void the warranty."

We do that kind of testing on every valve we bring in, it is a lot of fun seeing what will break first.

You've got a great job .
