Before You start

Starting the Work

You must ensure you cover your furniture and other possessions for protection. During the work, your water service will be shut off. The plumber should be able to work so that the water will be shut off for a short a period as possible during the day. So you have the least water supply disruption.

Know your pipes

A major decision you and your plumber will have to make before you move on with repiping your house is the kind of material to use. You have three choices – copper, CPVC, and PEX. Each of these has its advantages and disadvantages. Also, a plumber may have his preference and recommend it for your project. So, an understanding of each type of pipe will help you make the right choice.

Pros and cons of using each type.

Copper pipes

Copper pipes have been in use for decades and are the oldest type of piping in use. Many plumbers and builders prefer copper pipes. They are more durable than PEX and will not corrode like steel pipes. It gives you the best plumbing system and not likely to contaminate your water supply.

A copper plumbing system can last 75 to100 years. It is resistant to earthquake shocks. But the industry trend lately has been toward the use of CPVC and PEX. They are alternatives in remodels and new constructions.

This trend may be due to some disadvantages which include relative cost. Copper is more expensive. And the price changes often since it is a traded commodity. Installation of copper pipes also requires more work.

CPVC (Chlorinated polyvinyl chloride) Pipes

CPVC pipes are the common choice for remodels and repiping. These pipes came on the market in the 1960s and since then have been gaining popularity. These pipes are easier to install than copper pipes. They are also suited for existing buildings. They are not as long-lasting as copper pipes but should last at least 50 years.

CPVC is cheaper than copper and safe for drinking water. It can be used for hot water and is resistant to acid and other chemicals. But it can crack in earthquakes, so it is not suited for earthquake-prone areas.

PEX (Cross-linked polyethylene) Pipes

PEX is the latest piping material to enter the market. Its use started in new European construction before use in the United States started in the late ’90s. PEX is versatile, flexible, and easy to work with because of these qualities. These features, make it a favorite among modern builders.

But PEX is new, and it is not known how long a PEX system will last. It is more cost-effective than copper pipes. Its flexibility makes installation easy and removes the need for joint fittings. There are other pros, but it is not as durable as copper and will degrade in 30 days with exposure to sunlight.

Other Plumbing Upgrades to consider

Have plans for other plumbing upgrades? Do them with your repiping. You will save time and money with much of the prep already done for the repiping. Upgrades to consider can include low-flow fixtures, a tankless water heater, and smart water shutoff.

Low-Flow Fixtures

Repiping is a good time to give your home low-flow fixtures. With showerheads, faucets, and toilets using less water, your home’s value will increase. You will also have a lower water bill.

Tankless Water Heater

This would have a longer life, take less space than regular water heaters, and give you hot water nonstop.

Smart Water Shutoff

A smart water shutoff would be a good upgrade if you are repiping to change old and leaking pipes to cut out water waste.
