plumbing polybutylene

Plumbing polybutylene - When applied as a pure or reinforced resin, it can replace materials like metal, rubber, and engineering polymers. It is also used synergistically as a blending element to modify other polyolefin’s' characteristics like polypropylene and polyethylene. Its specific properties are used primarily in pressure piping, flexible packaging, water heaters, compounding, and hot melt adhesives. These catalysts also contain special modifiers, organic compounds belonging to the classes of esters or ethers. The pre-catalysts are activated by combinations of organoaluminium compounds and other types of organic or organ metallic modifiers.

Plumbing polybutylene is a type of plastic pipe manufactured for water supply in residential homes from 1978 to 1995. Unfortunately, this plastic piping is notorious for micro fracturing, split pipes, and subsequent home damage (and settled class-action lawsuits). It is estimated that about 7 to 10 million homes in the U.S. had poly installed during this near 20 year period. The last year you will likely find a home with poly is in 1996 due to built up supplies. Poly was also used for main water lines — from the house to the street — in single-family homes.

Although no regulations require the replacement of polybutylene piping with other materials, many plumbers recommend doing this at the cost of several thousand dollars. Leaking can happen without warning and can result in flooding and serious damage to a home's interior if it is not immediately stopped. PB pipes installed behind sheetrock can leak unnoticed for long periods and cause mold and water damage. Intern CHI believes it is far cheaper to replace polybutylene pipes before they fail and release their contents onto floors, appliances, and furniture.

Plumbing polybutylene was commonly used when installing a plumbing system in homes constructed between 1978 and 1995. Polybutylene resin is a saturated polymer that can be molded into several forms and shapes. It won't crack under pressure. It's flexible, and in general, is resistant to chemicals, acids, alcohols, and fats. It doesn't rust, won't calcify, and transmits low noise. Meaning it was thought to be the perfect solution for replacing traditional water pipes. And with the housing boom that occurred during this period, this low-cost alternative was introduced into the marketplace, where it remained for a couple of decades.

First, we must put something out there: there is no guarantee that Quest polybutylene plumbing will fail. While studies have shown at least some small amount of a causal link to polybutylene plumbing being risky, the truth of the matter is that any material can fail. Even modern plastics, copper, galvanized steel, and other materials that have long been utilized for their durability and longevity will eventually wear out with continual water exposure. Quest piping has been shown to fail at a higher rate than many other materials.

Even if you know you have poly pipes, you still can't tell what condition they're in just by looking at or squeezing them because the problems occur inside the lines. Failures may occur in systems with plastic fittings, metal fittings, and manifold‐type systems that look fine even to the trained eye. You must prioritize your home maintenance requirements and budget accordingly. Unlike most other maintenance issues, delayed replacement of poly may have substantial consequences. Due to the many documented cases of leaks, plumbing polybutylene experts recommend replacing poly pipes.

There is evidence to suggest that the presence of chlorine and chloramines compounds in municipal water (often deliberately added to retard bacterial growth) will cause deterioration of the internal chemical structure of polybutylene piping and the associated acetal fittings. The reaction with chlorinated water appears to be greatly accelerated by tensile stress. It is most often observed in material under the highest mechanical stress, such as at fittings, sharp bends, and kinks. Localized stress whitening of the material generally accompanies and precedes the decomposition of the polymer.

Plumbing polybutylene usually has a grayish-blue appearance, but it can also come in silver, cream, or black — one region of the country typically has the same color.

In my neck of the woods (the D.C. area), poly usually has the typical bluish-gray appearance. One surefire way of identifying polybutylene is to look for the PB2110 mark stamped somewhere on the pipe. You can also take plumbing for more information.
