Question: Should I Use PEX Or Copper?

Why Copper is better than PEX?

Copper is more likely to freeze and break.

One of the biggest disadvantages of copper pipes is their tendency to crack if the water inside freezes and expands.

Having a degree of flexibility, PEX is able to expand if the water inside it freezes, making PEX more resistant to freeze-breakage..

What lasts longer copper or PEX?

PEX pipe, on the other hand, is a much more durable and longer-lasting building product. PEX will not pit, scale or corrode like copper can. … So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.

When did they stop using copper pipes in houses?

Is PEX OK for drinking water?

The inner pipe for drinking water is made of a plastic called cross-linked polyethylene (PEX). … There are no health risks associated with drinking water from PEX pipes. A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time.

Should I use PEX A or PEX B?

Flexibility – PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.

Is PEX crimp or clamp better?

Crimping and clamping create equally reliable seals that will not leak when performed properly. … Stainless steel clamp rings resist corrosion more effectively than copper crimp rings, which can be a major benefit in direct-burial applications. PEX clamps also tend to be easier to remove.

Can Blue PEX be used for hot water?

Red PEX pipe carries hot water. Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).

Can SharkBite fittings be used on copper?

SharkBite brass push-to-connect fittings are compatible with PEX, Copper, CPVC, PE-RT and HDPE pipe. SharkBite fittings come with a PEX stiffener pre-loaded into the fitting for PEX, PE-RT and HDPE. The PEX stiffener does not need to be removed for Copper or CPVC applications.

Can you use PEX with copper?

The traditional way of connecting PEX to copper involves using a threaded sweat adapter on the copper side (to connect with the PEX fitting) and soldering to create a watertight seal.

What is the best type of PEX to use?

Most plumbing applications, especially those involving potable water, call for the use of non-oxygen barrier PEX, offered in several grades. PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures.

Why is PEX plumbing bad?

PEX failures Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation. Furthermore PEX pipe is vulnerable when it comes in contact with such solutions as petroleum products and oxygen. It can leach toxic chemicals from pipe material also.

Why is PEX banned in California?

It was banned because water quality studies showed that chemicals from PEX pipe were leaching into the drinking water. California often bans anything that poisons drinking water, especially if it puts residents at unnecessary exposure to carcinogens or anything that could cause birth defects.
