steel pipe
The type of piping varies from consumer to consumer, but there are three types that can be used for sprinkler systems: Steel, Copper, and Plastic.
Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. 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.
Nowadays, PEX tubing is quickly replacing traditional copper and galvanized steel pipes and is an exceptional option for underground piping.
Crimp fittings require copper or stainless steel crimp rings and a PEX crimp or clamp tool. Crimp fittings are compatible with all types of PEX tubing, except for PEX-AL-PEX. Crimp fittings are preferred for many applications since they are widely available and are the most affordable.
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.
PEX A is made using the Peroxide, or Engel, method. PEX B is formed using Silane, or Moisture Cure, method. This is the most common PEX pipe type out there. PEX C is created using the Electronic Irradiation, or Cold, method of cross-linking.
PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures. PEX-B is slightly less flexible and less freeze-resistant.
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. Then make short runs of one-half inch PEX water line tubing to each fixture.
Does PEX Pipe Need To Be Insulated? Yes, although PEX pipes can withstand freezing temperatures better than other pipe materials – but they are not freeze proof! If the temperature drops below 20 degrees Fahrenheit your pipes have a very good chance of freezing.
PVC and CPVC pipe filled with water, sealed and placed in a freezing environment typically will not crack. The pipes will expand to absorb the net volumetric expansion of ice.
200 degrees Fahrenheit
Due to its flexibility, PEX has a small margin of expansion under the damaging pressure caused by ice formation. If the weather gets cold enough, PEX pipes can and will freeze like any plumbing. However, PEX may be less likely to rupture as a result of freezing.
PVC pipes are in danger of freezing when surrounding temperatures approach 20 degrees Fahrenheit. Ice begins to form and gradually blocks the pipe. Water damage from a burst pipe is expensive. To avoid dealing with burst pipes, prevent them from freezing.
