Ask around. Ask your friends, ask your neighbors and get referrals. Nothing is more powerful than the testament of someone who has had a local plumber in their home and can speak to his/her capabilities.
Four: References - It is always a smart idea to get references from a plumbing contractor because this will help you find out if they can be trusted to do the work they promised to and if they do a good job.
Some trustworthy plumber valves do not take washers and therefore you cannot repair them. If you have a washerless shut-off valve that leaks it will need to be replaced. You will need: a propane torch, solder, flux, sandcloth, a wire fitting brush, a small section of copper pipe (most likely 3/4" I.D.), a slip coupling (again probably 3/4") and a shut-off valve. I would highly recommend installing a ball valve with a drain on it as opposed to a washer style valve. If you purchase a decent quality ball valve it will last a very long time.
Not all faucets have or even need interior shut-off valves. If your valve is a "frost-free" style of valve then you wouldn't need a shut off inside. Frost free valves are a style of valve in which the Trustworthy plumber water shut off for the valve is located internally in the valve inside the house. The use of a frost-free valve is best suited for locations in which an internal shut off valve is inaccessible such as a location where the walls and ceilings are all finished. This style faucet can leak over time. If you have a frost-free valve that is leaking you will need to replace the washers internally on the valve to prevent the valve from freezing and bursting.
Finding plumbers in your area does not have to be difficult. Usually they have listings for your area on the web or through other informational books that list businesses in your area. This way you may connect with a Local plumber for all your plumbing needs.
Whether you choose a freelance plumber or a plumbing company, verify if these individuals have plumbing licenses. Licenses guarantee that you and your neighbor's properties are insured in case something goes wrong.
Hourly fees are another thing you want to check out before you hire a plumber. Call around and get a few estimates for a job. Ascertain if the plumber is willing to sign a quote and give you a price warranty before he begins working. You should also find out if the plumber will require you travel time to and from your job and how they will compute that time and prove it to you. Giving you a precise price may be challenging, but any plumber who can't give you a comprehensive explanation of how you will be billed with an estimate of the cost should be avoided.
