Hi folks,
I recently replaced two old cheap faucet shut-off valves (they were the kind where the "speedflex" hose is pre-attached to the valve) with some new 1/4 turn valves that have threaded connections for supply hoses.
The old ferrule and compression nut would not come off the pipe, so I just intended to attach the new valve with the old ferrule and nut (they are the proper size). Some guys at my local plumbing supply house said this would be OK. (is it really?)
Then I hit a snag. The "socket" part of the old valve was much deeper than the socket the new valve, so the new valve would not make contact with the old ferrule when I slid it onto the pipe. I was advised to simply saw off enough of the pipe end to shorten the pipe and allow the new valve to make contact with the old ferrule and create a proper seal. I did this, and completed the job with no leaks, but it was NOT EASY sawing through the pipe with a small saw in close quarters.
We're planning on replacing the low quality "builder's grade" faucets in the other bathrooms, but I'd like to first replace the supply valves for those as well so I can install braided stainless hose which will make the new faucet connections easier (I don't want to reuse the old "speedflex" hose, which I'm told will eventually break after enough movement). After my first experience, described above, I'm thinking I might be better off hiring a plumber.
I have a few questions:
What is the proper way to do this job (i.e. when the ferrule won't come off)? Is what I did OK?
I've read I can get a "puller" tool to remove the old nut+ferrule. If I do remove the old nut & ferrule, is there a chance the old pipe is crimped and therefore a new ferrule wouldn't seal properly if it straddled any part of the crimped area?
Would it be best to have some sort of threaded connector (sorry, don't know the terminology) soldered onto the existing pipe so I don't have to fool with any more compression fittings and stuck ferrules?
How would a pro do this job?
Last, what does a plumber typically charge for a "standard" replacement of a set of 2 shut-off valves for a faucet? I realize every job is different, but even a ball-park figure is OK. Although I did the job for one faucet, the stakes are higher for the next ones because they are upstairs and a leaking connection will be a bit more costly... so I'm thinking about hiring a pro,
Thanks for any advice.
