Q:Plumbing Help, New Faucet install!!!?
Here's the bottom line, as I see it. Shut off the water to the house at the service valve out front or, if that valve doesn't work properly, shut it off at the meter. Get a tubing cutter and cut off the service valve under the sink as close to the valve as you can. Do not use a hack saw, use a tubing cutter. Home Depot sells new service valves that are compression fittings to slip over the pipe coming out of the wall or floor. Take the old valve with you so they can help you with the correct size. You'll need to cut off both valves. When you buy the new valves, buy some new armored hoses to connect your new faucet to the new valves. You'll need a couple of wrenches to install the new valves and hoses, and you may need a basin wrench to install the new faucet. Consider the tools an investment and the valves and hoses maintenance expenses. Once you've done one successfully you'll never be intimidated by that type of job again. Good luck.
Q:Kitchen pots and faucets with what material is good
Faucet is good or bad mainly look at the core material, pure copper core is the best, followed by stainless steel, the appearance of the best material is stainless steel or galvanized. More durable and on the grade.
