Can you insulate PEX tubing?
PEX tubing is susceptible to cracking when it’s exposed to freezing temperatures or ultraviolet light. Covering the tubing with a flexible insulation will eliminate both hazards while allowing the PEX to expand and contract with fluctuations in water temperature.
Should Poly B be replaced?
Plumbers recommend replacing Poly-B pipes with something else (such as PEX or copper). Not only might you have difficulty getting insurance, but Poly-B plumbing can discourage potential buyers from purchasing your home if you ever decide to move.
How much does it cost to replace poly B?
The average price of poly-b replacement is usually between $5,000 and $15,000. Although this is a considerable investment it can save you spending even more when dealing with damages from a burst pipe.
When did they stop using Poly B?
Some manufactures stamped on the pipe that it was not to be used on continuous circulating hot water lines. Poly-B piping was produced from polybutylene resin and in the spring of 1998, manufacturers stopped producing Poly-B piping because suppliers suspended production of this resin.
What’s the difference between PEX and poly B pipes?
Poly-B pipes are not the same as PEX pipes. PEX is short for “cross-linked polyethylene,” which is a different type of plastic than polybutylene. PEX is manufactured using a different method, and the result is a plastic pipe that’s much better for home plumbing.
Is it safe to insulate PEX water pipes?
Limiting the exposure risks and insulating PEX piping reduces water pipes’ chances of bursting or leaking and causing tiresome and frustrating outcomes, which may be costly to repair, not to mention the potential necessity for piping replacement.
Which is a better insulator PEx or copper?
Although PEX is a better insulator than copper, having hotter water come through the pipe faster is a good thing. The PO did it in my house, but we have a well. He insulated the cold-water pex wherever he could, probably because it sits in a pressure tank and he was hoping it would stay cold.
What are the problems with poly B plumbing?
The first problem with Poly-B has historically been the fittings. The fittings, used to connect one pipe to another, are often plastic. These fittings are prone to cracking and leaking over time. In some cases, the fittings weren’t installed correctly. They’ve often been over-tightened, causing the pipes themselves to crack.

What kind of insulation is best for PEX pipes?
Tips for Insulating PEX Pipes. It is important to choose the right insulation material. Because PEX piping is flexible, it is often used in angles, loops, or other non-linear shapes, which makes it imperative to have equally flexible insulation material. Foam is used most commonly, and generally works well.
When to switch from poly to PEX water piping?
The piping tends to deteriorate quickly in places where they have chlorine in the water like most municipal water supply systems. Replacing Poly with a PEX A pipe is the best option so far because their average life span is up to 50 years.
Is there a problem with poly B pipes?
Although the system has performed as designed and intended in many homes, Poly B has experienced failures impacting the way insurance companies may view homes that have these pipes installed. All plumbing systems may fail without warning and cause damage.
