Replacing A Valve

Globe, Gate and Ball Valves

brass ball valveA plumbing system should have a main shutoff valve that controls water to the whole house and intermediate shutoff valves that control water for various areas of the house. According to the plumbing of Littleton experts, there also should be shutoff valves on the incoming cold supply line for a water heater and stop valves (also called fixture shutoffs) that control water leading to individual faucets and appliances.

If an old shutoff valve – usually a gate or globe type – leaks at the packing nut, make sure it is all the way open or close. If it still leaks try tightening the packing nut with pliers or an adjustable wrench. (Don’t crank down too hard, or you could crack the nut).

Stop valves

Replacing a valve with brass will stand the test of time, or any a faulty stop valve with a ball-type model, which cost a little more but is very reliable.

A globe valve inhibits water flow even if it is in good working order. Replacing it with a ball valve may increase water pressure.
