Tub + Shower faucet installation

Hey everyone,

 

I'm in the process of finishing my master bathroom remodel. I purchased a new tub and shower set (SKU 649927). I'm replacing the existing old fixture behind the shower surround that connects the 4 pipes together, hot, cold, 1 to faucet, 1 to shower head. I had to install an access panel in the closet behind the shower surround to gain access. I cut out the old fixture using pipe cutters. I cleaned the pipe ends thoroughly making sure to remove all burr and sharp edges. I'm using 4 sharkbites (SKU 937300) with teflon tape to connect everything together.I turned the water back on and of course I had a leak....on the threaded end of the sharkbite where it connects to the fixture. Its't not a major leak but a leak. I only hand tightened the sharkbites when I connected everything together. Maybe this is the problem? I would appreciate any help/advice to resolve this please. I don't know how much it would cost to get a plumber to fix the problem, aparently they're expensive. Please help.

Hey Paddy77, Newf out of Chicago here.

I think we got our wires crossed a little bit...

 

Plumbers dope (or teflon tape) needs to be used on threaded connections where the THREADS are the sealing point.  In your case this is the threaded side only of the SharkBite connectors.

You should generally use 2 wrenches (in opposition of each other) to securely tighten these threaded fittings.  One wrench on the SharkBite, and the other on whatever it is threaded into.  This allows you to torque the threads together without twisting the rest of your plumbing work.

 

The "push-in" or compression side of a Sharkbite is sealed internally with an "O" ring.  No pipe dope or tape (or anything else) should be used as a sealant.  Just make sure that the pipe end is square, clean and not crimped in.

 

I hope this helps!

Yes – you’re right Paddy77 – you need to apply more effort than hand tightening the Sharkbite fitting.  You have done a great job so far on remodeling your master bathroom and now we can get you across the finish line in style!

 

Make sure there is Teflon tape on both ends of the Sharkbite.  Attach the fitting and hand tighten.  Then use a monkey wrench, crescent wrench, or vice grip to tighten further (90 degrees or until you feel the tension). 

 

Clean up the leak and check for mold before you close up the access panel.  I think this will solve the problem - please tell me how this works.

 

Best wishes on this project and please send us pictures of the finished bathroom!

Hi Designingwoman, thanks for the help. I can only put teflon tape around the threaded end of the sharkbite since the other end is a compression fit for the copper pipe. What about using teflon liquid (plumbers dope)? How does that rate against just using tape alone? This bathroom remodel has been a pretty big project....many many trips to H Dep!! New tile floor, trim, mirror, vanity, faucet, lights, paint, accesories, even a new skylight......the finishing line is near, just to cross this final hurdle!

Almost there paddy77!  Teflon liquid (plumbers dope) will be fine - just squirt an ample amount on the compression fitting.  I understand from my plumbing specialist that most plumbers prefer the liquid over the tape. 

 

Make sure that the threaded end is sufficiently tightened.  That is the most likely source of the leak.  And don't forget to check for wetness or potential mold. 

 

I am impressed - a skylight in the bathroom - it sounds like you have created a spa!  PLEASE send us photos since we can’t wait to see your handiwork.

Hey guys,

So I took everything apart yesterday, got some plumbers dope, put it on the threaded ends of the sharkbites, tightened securely with wrench, put everything back together, turned the water back on - NO LEAKS!!! One thing the associate told me at H Dep was to remove the little white plastic ring or collar inside the sharkbite before connecting to copper pipe. I've tried attaching/inserting is a pic of the finished installation with new access panel but for some reason I don't have the option since I have a 64-bit machine. Thanks to Designingwoman and Newf for your advice!!
