Q: Why does my toilet keep refilling?
A: There are a number or possible causes for this problem. It could be that the flapper isn't seating properly. The flapper can accumulate a thin layer of scale or a slippery film over time which can cause the water seal to fail. Cleaning or replacing the flapper will correct this problem. Another cause can be a kinked or tangled lift chain which is easily fixed as well. If neither of these is the problem it could be a worn out flush valve. There are a number of different kinds of assemblies available at any hardware store, plumbing supply company and most discount centers and installation is fairly straightforward.

Q: Why do my water pipes rattle?
A: The problem may be water lines that are not properly isolated from the structural elements of your home. If this is the case, the motion of water moving through the pipes may be transferring to beams, joists or studs in or beneath your flooring or in the walls. If the pipes are accessible the solution may be as simple as inserting an insulating material between the pipes and the structural elements they are touching. If your pipes only rattle when the water is turned on or off it may be that you need to install a water hammer arrester which will eliminate the jolt caused by quick closing water valves. This problem can be somewhat tricky to diagnose and you may want to consult a professional plumber.

Q: How do I choose the right size water heater for my home?
A: The answer depends on a number of factors including the number of people in your household, number of bathtubs and / or showers, whether your home has a dishwasher, washing machine or whirlpool bathtub and whether your water heater is a natural gas or electric unit. Typically, for a family of 4, a 40 gallon gas water heater will be sufficient for your needs. If your water heater is electric you would want to consider a 50 - 60 gallon unit. Consult your plumbing contractor or water heater dealer to ensure the unit you choose will serve your needs.
