What's The Story On Qest Plumbing In A House?


Found this stuff all in a customer's house. He already doesn't like it and feels it's nothing but problems waiting to happen. He showed me where his neighbor a plumber had put some sharkbite fittings on it to hook up his hot water heater in the basement and was explaining to me that his plumber said this is the way it's done. I'm not excited in anyway dealing with shark bite fittings and certainly not having them buried in the walls of a remodel.

Looking at this stuff on the internet there seems to be a lot of different opinions of it and how to deal with it. If we do anywork on his project the most plumbing would be involved in connecting a new tub valve to the stuff.

What's the real way to connect copper to it? Would anybody be comfortable warrantying their work joining to this stuff? I've read that others will not offer any warranty to a customer with anything involving dealing with Qest. I think it goes by QestPex too.

If it is Qest polybutelyne stay away from it, it was involved in several class action lawsuits back in the day because it is a flawed system prone to failure. Mobile home suppliers usually stock fittings for it as it was very widely used in the manufactured home industry.

Re: What's The Story On Qest Plumbing In A House?


Back when it was used in the buildings I was working on, everything was done with crimp rings and fittings, as I recall. No Sharkbites back in the 80s, that I'm aware of.

Re: What's The Story On Qest Plumbing In A House?


My plumber called me back, he says that dealing with it is no big deal, however, it's only a matter of time before their house floods from the stuff. Of course he recommends them removing it all, says he just did one for about $2500 bucks not including the repairs to the walls.

How is this for a disclaimer if we do take the job -

Quote:
*Customer has qest water lines in house. Rocky Mountain Bathrooms makes no warranty to existing qest water lines exposed and/or disturbed during renovations or qest water lines not exposed and/or not disturbed during renovations. Rocky Mountain Bathrooms makes no warranty to the connections between the existing qest lines and new water lines installed. Rocky Mountain Bathrooms only warranties the new water lines and connections beyond the connections made to the qest lines.

I would say that looks good as far as a disclaimer.

Why would you ever warranty anything before the point your hookup begins?

Re: What's The Story On Qest Plumbing In A House?


I wouldn't and from what I've heard in this case with this stuff you better make it pretty clear that you won't.

If you've been in business any amount of time, you know as well as I do that customers like to play the whomever touched it last owns it game. This crap develops a leak ahead of our work in the same room and I'm not going to be on the hook for it, just because we distrubed it, and until I hear otherwise from enough pros, it sounds like the connections between the stuff and copper aren't reliable either. I want it clear to the customer that they aren't and I'm not even warrantying the connections to it.

They also make these Qest couplers. Never used them before, so I'm not sure what to think about them. They say that they can be used to connect Qest and copper.

Re: What's The Story On Qest Plumbing In A House?


I hear you on the "you touched it you own it" issue.

I would be interested if anyone has a good disclaimer regarding existing Qest.

This is a disclaimer that is currently in our contracts, "
Contractor will connect its fixtures to the existing plumbing and assumes no responsibility for the condition of existing shut off valves, traps, or other fittings. Additional plumbing work or delays due to preexisting conditions including but not limited to, faulty or non-existent shut off valves, lead pipe, polybutelyne pipe, high rise or condominium requirements or any other preexisting condition may require additional cost. Contractor will make every effort to identify and notify owner of any such condition prior to commencement of installation but cannot be responsible for hidden, concealed, or unknown defects. "

My plumber uses those for temporary fittings but he said he will not leave them permanantly (not sure why never asked). I have seen them last as long as a month or so with no problems.

I can't see that being rated to be installed in a wall.

We used to refer to those fittings as "squeak" fittings because of the noise they made when they were tightened. And yes these fittings were total junk! Only hacks and homeowners would use them. They gave us a lot of service calls because they split.

Are you also referring to the tubing or just the fittings? Are the fittings compression or crimp?

its a PB x PEX coupling

PB has a different ID than PEX

both are CTS OD....

you use the same crimping tool for the pipe but the fittings are different....
that fitting allows the joining of the 2 different pipes

Re: What's The Story On Qest Plumbing In A House?


Hope it's ok to jump in

(me------>nOObie here)



The PEX has 3 ribs, the Polybut has 7 ribs, for quick identification. Have been a fully licensed and HUD certified mfd-mobile home serv co and plumber for 28 years. Lots of plumbing under my belt To date, over 30,000. It has been my happy choice to do charity jobs or discounted jobs and help those in need. Lots of people got hit hard over the lives and are happy in a mfd or mobile home. They don't have a lot of money. I have installed over 6,500 Qest grey compression fittings over the years with nary a leak. The Govt. asked me four years ago in a study they conducted to write up my personal review on them. I went back to the original jobs I had done, through those spanning about 20 years time. Not a leak at all, ever. The Govt. even asked if I would install a couple behind walls. Just checked those fittings last month, no leaks there either.
Purr-sonal opinion, the "Qest = bad fitting"..... is (I think) a bad rap.

Sharkbite:

I have preferred to sit back and wait on those, but I was already proved right in my assumption. About 40 of my licensed plumber friends said they have all failed them. I stay with the PEX brass/Oetiker SSC clamps and Qest grey comp fittings. Consistent, quick, efficient, inexpensive fittings every time.

PS Thanks for a great place to come to, I have been lurking a few months now reading up, but wanted to share my experiences with the PEX and Qest.


(don't kick me out please )

That sounds like a good disclaimer, but the "every effort" part sounds a little questionable. How do you define "every effort" and why force yourself to follow through on such extreme language?
