DOes anyone know how long it should take a licensed insured plumber to change a toilet shut off valve?

I just showed my young son how to do one @ my mother in laws home & took only about 15 min and I took my time explaining things to him. A plumber can do that blindfolded in less time but they do have to account for a min amount of time to cover travel expenses, so expect a min service charge I would expect maybe 30min charge would be a safe guess...

Well one guy said it takes 40 minutes. I just figure if I am paying for an hour then maybe I can get all 6 of them changed in that hour!

Thank you very much for your response.

Maybe you can work something out since he is already out there, doesn't hurt to ask. It's a very simple job, don't you know any handymen that are capable? The valves are very cheap only like $5, save some money and have a friend do it, it really is very simple...

I live in a condo and I have to have them turn the water off. They will only turn the water off for a licensed insured plumber. I am starting to think to have him do the one and then I can go around and do the others myself.

If you feel confidant in doing that, problem is if you encounter any problems they won't turn the water back off for you and you will have to pay the plumber to come back out. Here is a link to a site that shows how to replace the valves with good pictures. How to Install Shut Off Valves | DoItYourself.com (http://www.doityourself.com/stry/installshutoffvalve)
I also recommend replacing the valves with the type shown in the illustrations called ball valves, they are much more reliable then traditional gate valves commonly used and only a couple $$$ more and a lot easier to operate should you ever need to...

A friend that has done some work for a plumber said that I should replace them all with 1/4 turn valves.
I am not sure sure that I would replace them on my own.

1/4 turn valves are in fact ball valves, they have less moving parts, are easier to operate and are less prone to leakage then gate valves.
Good Luck. Bill...

Oh good. See that is how little I know. Thanks I appreciate your help and suggestions!

Never hurts to ask, hope everything works out well for you...

Make sure you know what type of valves you have now. If compression, then yes, they are usually simple to change, if threaded, you may run into problems with rotten pipe threads at valve or in wall. They may even be sweat valves, which would require more time to replace. Please let us know what type valve you have, maybe you could post a pic here. If you are looking to replace the rest by yourself, I would watch and see if the plumber has any problems with the one he installs. But really, while you have him there, it would probably be best to just have him replace them all. The more you turn the main water on and off, the more likely you are to have problems with plugging of toilet fill valves, and faucet aerators, etc etc. Good luck and please let us know what you decide and how things work out. Take care,
