It is a sealing putty used for a variety of tasks including to seal basket strainers, garbage disposal rims and tub drains.

It cleans the surface prior to soldering. It prevents the oxidation of the metal. And it allows the solder to flow freely.

Health codes require lead-free solder.

All pipe surfaces should be thoroughly cleaned with pipe cleaner. The cleaner is formulated to remove surface dirt and any oil or grease that exists on the pipe from the manufacturing process. Primer/cleaner and primer contain more aggressive solvents and will soften the pipe surface to allow the solvent cement to penetrate more effectively. Primer is often required by plumbing code and sometimes a purple colored primer (purple primer) is needed.

They reduce friction in assembly and provide a watertight seal.

There are three ways to repair cracked copper pipe. One is to use plumber's epoxy putty on the area. Two would be to solder the crack and third, if you have enough, cut the bad section and put in compression fitting.

They do the same job, but Teflonâ„¢ tape is easier to work with and makes a cleaner joint.

The refill valve, the flush valve and the trip lever.

CPVC can be used on hot and cold lines, while PVC is for cold water only. PVC is usually used as a drainpipe.

If you are replacing an existing unit that has worked well for a number of years, the old size should work fine. Otherwise, 1/3 horsepower will handle limited use once a day. A standard 1/2 horsepower will normally suffice for general use. Heavy-duty 1/2 horsepower units and larger are designed for a large volume of garbage.

Most people base their purchases on the size of the storage tank, but a better method is to first estimate how much hot water you will need during the peak hour of use. This is referred to as the first-hour rating (FHR) on the Energy Guide label posted on new water heaters. Typical hot water use is:

   * Showering 3 gallons/minute
   * Bathing 15-25 gallons per bath
   * Shaving 1-3 gallons
   * Washing hands 1/2-2 gallons
   * Washing dishes 4-6 gallons
   * Running dishwasher 5-20 gallons
   * Running clothes washer 25-40 gallons
   * Cleaning house 5-12 gallons
   * Food preparation 1-6 gallons

These are almost always 1-1/2 inches. The 1-1/4 inch traps are for bathroom lavatories.

This is a safety device that will open in case of high pressure or temperature.

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.

You should use a dielectric union. This will prevent electrolysis from occurring, which deteriorates the copper tubing.

Yes, a strap wrench grips the pipe without teeth.

The faucet mounts with the fixture holes set 8 inches apart. It’s important that you buy the right size faucet to fit.

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.
