Frequently Asked Questions
My showerhead has a buildup of a white substance around the spout. What should I do about that?
The white substance is actually mineral deposits. To remove the mineral deposits from the showerhead, pour a cup of vinegar into a plastic bag and then place the bag over the showerhead fixture and leave it in place overnight. The next day, remove the bag and use an old toothbrush to scrub off the deposits.
What is plumber’s putty?
It is a sealing putty used for a variety of tasks including to seal basket strainers, garbage disposal rims and tub drains.
What is the purpose of pipe joint compound or tape?
They reduce friction in assembly and provide a watertight seal.
Which is better for sealing—Teflon™ tape or thread joint compound?
They do the same job, but Teflon™ tape is easier to work with and makes
a cleaner joint.
Is there a wrench I can use that will not damage the brass, aluminum or other soft material?
Yes, a strap wrench grips the pipe without teeth.
What is the difference between PVC and CPVC plastic pipe?
CPVC can be used on hot and cold lines, while PVC is for cold water only. PVC is usually used as a drainpipe.
How should I cut plastic pipe?
Any fine-tooth saw will work, but make sure you remove any burrs.
There is water leaking from my water heater. What’s the cause?
The pressure relief valve could be leaking. Try operating the valve to see if it will stop. It also might need tightening. A gasket around the heating element may need to be replaced, or the tank could be rusted out, which requires a new hot water heater.
