What size PEX is used for water lines?

PEX is available in 3/8- to 1-inch diameters. It’s a good idea to install 1/2-inch or 3/4-inch PEX for your main lines for adequate water flow. When replacing old water supply lines with PEX the standard is to use the same size plumbing, although you can transition from 3/4-inch to 1/2-inch plumbing with an adapter.

Can I install PEX myself?

No. You can install PEX fittings supply just like you would other pipe, with main lines and branches to each fixture. But you lose a lot of the benefits of PEX with this system since it requires so many fittings.

Can you use PEX fittings on regular pipe?

What to do if you have a hole in your PEX pipe?

Several years of even the slightest movement can wear a hole in PEX pipes, especially if they’re rubbing against something abrasive. You can protect your pipe with abrasion clips, cover the pipe with inexpensive pipe insulation, or enclose it with a larger pipe.

What do I need to make a PEX supply connection?

Connections for most PEX supply jobs require a special tool. There are several PEX supply connection methods, but only two affordable enough to be practical for DIYers: crimp rings and cinch clamps. Crimp rings are a band of metal, usually copper, that you slip over the fitting and compress with a crimp ring tool.

How do you splice PEX into plumbing pipe?

How Do I Splice PEX Fittings Into My Existing Pipe? There are several methods. The easiest is to cut out a section of plumbing pipe and slip in a stab-in tee (left). SharkBite is one common brand of stab-in fitting. This method doesn’t require soldering, which can be a big time-saver.

What kind of fittings do you need for PEX pipe?

For each of the following methods of connecting, the fittings and connectors must be an exact match to the size of the PEX pipe. Hundreds of types of fittings, usually brass, are available for connecting PEX to existing copper or steel pipes, and for making connections to fixtures.

What’s the best way to make a PEX connection?

Slide the ring into position over a point where the pipe and the fitting overlap. The distance from the edge of the pipe varies, based on material type and manufacturer. Using a crimp tool, compress the crimp ring until the tool stops. Use a go/no-go gauge to verify each connection has been made properly.

How do you connect a hot water faucet to a PEX pipe?

Turn the nuts on the faucet connectors counterclockwise onto the threads of the faucet stems with the blue pipe on the right (cold) stem and the red pipe on the left (hot) stem, if applicable. You do not need to use Teflon tape or pipe dope on the threads because the fitting contains a rubber washer that seals the connection.

What’s the best way to connect a PEX cinch clamp?

Step 1: Position the cutter perpendicular to the PEX pipe and make a smooth, clean cut. Slide the PEX cinch clamp over the pipe. Fully insert the PEX crimp fitting into the pipe. Slide the cinch clamp toward the fitting so that it (edge of the clamp closest to the fitting) is positioned 1/8″ – 1/4″ from the end of the pipe.
