I have a couple shut off valves I want to replaced since they are aged and it's gate valve. I want to replace them to brass ball valve.

1" Main shut valve + 1" PRV straight inline installation, space is good. Estimated 2 hours

Laundry (hot and cold) shut off 0.5" and backyard hose shut off 0.5". They are near to each other. One might be a little tight on space. Estimated 3 hours total max

Am I about right on the labor time? I want to check if I am getting kill on quotes

Hello

There really is no way for us to estimate something like this (we would need to be at your house and count the number of bathrooms, number of floors, size of house, etc.). Travel time and time to pick up materials would also need to be factored in, and again, we could not guess at that, right?

Get 3 quotes and compare them...that is really the only reasonable answer here!

Good luck!

Mark
