Plumbing

[Crmzendrgone]

Does anyone know anything about plumbing? I have to replace the bathroom faucet and I have installed two cheap 10$ ones from wally mart and both keep leaking from the cold side. So I figure I would get rid of the flex tubing and install new steel breaded line but I have to replace the angle stops and I do not know if the standard piping out of the wall is a 1/2" or what cause I bought new ones for 1/2". Next question is how exactly does compression fittings work? I think the angle stops on there now are compression and someone told me that most of the time the little flaring will stay stuck on the pipe TRUE??? but the new ones come with all new parts. Also do I need plumbers tape on any of the fittings???? This is similar to what I bought but at a 90* angle. The second picture is a better representation of what I want.

what are the pipes that they are going on , copper , iron , pvc , polybutylene , let us know .

Oh good question I want to say copper? I'll take some pics.

if its copper, that is a compression fitting and not sweated on. if you wrenched down on the new hoses without holding the valve with a backup wrench, you could have put that wedding band in the compression fitting in a bind. i have seen that happen a couple of times. the fitting itself is not hard to replace unless the band is froze on there. that makes it quite difficult to try and remove and still be able to put the new band on.

Got it all finished. Thanks for all the advise I really appreciate it!!!

I was told that I can reuse the wedding band so I did and it works ok. I had a small leak but just had to redo the Teflon tape again. THANKS!!
I want to thank Hotrodpc and everyone else in this thread.

I'm glad you got it say im no plumber as well or no professional one when I was replacing my hot water heater I couldn't figure why the PVC fittings I was buying wouldn't fit well it turned out that hot water PVC is different it messed me up big times. I also went with braided flexible lines for the next time it should be a super fast job.

What Teflon tape? Shouldn't be any in that setup at all. The stop valves you have use compression fittings (1/2" to the supply side and 3/8" out) so there should be no Teflon or goop needed at all. In fact, Teflon might actually prevent a good seal.

Uh oh. I put some tape on the threads of the angle stops. That was the only way I got the hot side not to leak. So far so good. I hope.



Side matter related but has nothing to my repairs. The wife tells me when she runs the washing machine and uses the hot water setting that the pipes/hose in back vibrates as well as under the kitchen sink. So she was running it a minute ago and I found that it is the cold water piping not the HOT but only when she uses hot to wash the cloths. Does anyone know why that is, that it vibrates?

Where was the hot leaking, from the inlet (feed in) or the outlet side? If the inlet side, use a new compression ring and make sure you tighten it properly. If the outlet side, pull the connection apart and make sure the rubber washer on the hose didn't get damaged when it was put together. That's fairly common, because folks get the threads started on the nut, but don't realize the hose itself is angled to the side. The trick is to hold the hose firmly in place while you finger tighten the nut, then use a wrench on it. If you don't, odds are the rubber washer gets cut when you tighten down.

On the vibration problem, what's happening is you're getting some turbulence in the flow, called a "water hammer", due to the reduced pressure when both hot and cold are used at the same time. If possible, make sure the pipe or tubing is firmly clamped down as close to the tap as possible. If that doesn't fix it, and you can sweat pipe, add a water hammer preventer (basically it's a tiny expansion tank) to the line.

more commonly called a water hammer arrestor. can be bought in various size pipes so you wont need reducers or bushings.
