First time poster here guys, so bear with me.


I'm a DIYer who has embarked on a bathroom renovation. Most of the renovation is no problem for me, and I've already completed the demo, replaced and re-enforced the subfloor, replaced the walls, etc. My last wall panel to replace is the one that will be dealing with the plumbing for the shower. I'm upgrading from an old shower valve/faucet/shower assembly to a more modern one. The old one wasn't threaded, and just had the Quest pipe from the supply lines go over a male part on the valve, while a crimping device was applied over the top. Then for the lines down to the faucet and up to the showerhead, copper was used.

The new valve has threaded female parts on all 4 line attachments, so I'll have to be changing things in order to properly assemble it.

My question is this. What would I use as a good transition point from the Quest (because nobody sells it anymore) to Copper/CPVC/PEX? And which of those would be better in this application?

I went to my local Lowe's and Home Depot and they don't do ANYTHING with Quest and told me to go to Ace Hardware because they still carry some Quest parts. I grabbed what looked like a correct fitting which had Quest attached to a male threaded brass fitting. When I attempted to hook this up it leaked as if there was no kind of seal.

I then searched online for some possible solutions. I found Sharkbite fittings, and went to Home Depot to grab a few different kinds last night.

Here is one of the fittings I grabbed.




My problem is that I want to rid myself of Quest as much as possible. The bathroom I am renovating is on the main floor, and the supply lines run up to the 2nd floor bathroom as well. I', looking to buy a "T" fitting by Sharkbite and then run either Copper/CPVC/PEX to the shower from that fitting on each supply line.

Basically I'm curious if the Sharkbite would work on the Quest (the guy at Home Depot didn't think it would). And what material should I use the rest of the way to finish off to the valve?

The piping is 1/2-inch.


Thanks in advance!

In my opinion, and this is just an opinion, the sharkbite fittings will work perfectly with the quest pipe as long as you use the plastic insert that comes with the shark fitting. I have used them numerouse times on trailer homes for quick repair in the belly. Never had a leak on one yet. I really think shark bites are the best option for transitioning from quest to other materials. No guarantees here, but it has worked for me many times.
