Part of remodel planning for any room in your home that has pipes and faucets is to determine whether you have clogged pipes that need to be cleaned or replaced.

Pipes can collect mineral build-up or rust over time. In some cases, this corrosion or mineral build-up can reduce the interior size of the pipe by half, restricting water flow. If this is the case, you probably should replace these pipes as part of your remodeling project. Bathroom Remodeling Workbook by Dan Fritschen

It will cost less to do all of the needed work on a room at once. It also makes a world of sense to fix the pipes before you install new plumbing fixtures, cabinets and flooring. Without adequate water flow – no matter what the water pressure – whirlpool tubs, spa showers, and even toilets will not work properly. It is important then to check the pipes before your install new plumbing fixtures.

If you will replace pipes, here are a few tips to keep in mind:

— Plastic pipe is usually easier to work with than metal pipe.

—  PVC pipe can only be used for cold water. Be sure the PVC pipe you choose is approved for drinking water, if appropriate.

—  ABS pipe can be connected to several kinds of metal pipe, but is used mainly in bathrooms for waste removal and drains.

— PEX can carry both hot and cold water, and is a good choice for interiors.

— CPVC is mainly used for hot water; it is a good substitute for copper pipe.

— Brass can be used in the same ways as copper pipe in many cases.

— Galvanized steel was used for water supply lines, but it is susceptible to corrosion and mineral deposits. This might be what you are replacing.
