The price of a polybutylene pipe will depend on how big it is, if it has any alloys in it, and how long it is. Without this information, it is near impossible to give a quote on price.
Polybutylene pipe is a discontinued pipe.
I would say a form of pex plumbing
i would think that you could acquire a polybutylene pipe at sears, home depot, wal mart, or just any home appliance store. You will just have to look around maybe make a few calls
The most effective methods for repairing polybutylene pipes include using push-fit fittings, crimp fittings, or PEX pipe replacement. It is important to consult with a professional plumber to determine the best solution for your specific situation.
Polybutylene pipe and PEX are both types of plastic piping used in plumbing systems. Polybutylene pipe is known for its flexibility and resistance to corrosion, but it has a history of issues with leaks and failures. PEX, on the other hand, is more durable and reliable, with better resistance to chemicals and temperature changes. Overall, PEX is considered a better choice for plumbing systems due to its superior performance and longevity.
Its not bad as long as they are not leaking. Unfortunately polybutylene pipes have the best chance to start leaking at some point and it can be costly to repair.
There is considerable risk of pipe or plastic fittings splitting. Poly B has long been disliked for this, and I regularly get called to replace it with PEX.
until you clean the pipe
Polybutylene is typically made through polymerization of butene or butadiene monomers. These monomers are chemically bonded together in a repeating pattern to form a long chain polymer called polybutylene. The process usually involves high pressures and temperatures, along with catalysts to control the reaction.
As I understand it polybutylene hasn't been removed from the formal plumbing code, however the sale of polybutylene was quickly phased out in or around 1995 which is when the major class action lawsuit (Cox v Shell Oil) was settled for just shy of a billion dollars. As you likely know there have been countless problems with all variations of polybutylene pipes and associated fittings, and although it's still listed in the code, consumers should not consider this an endorsement of quality or performance.
They grey pipe you are referring too is polybutylene, it was the subject of one of the largest class action lawsuits in plumbing history and is no longer used. Transition to a different pipe depends on the method used for installation. This job may involve a considerable amount of repiping I recommend calling a licensed plumber. Check the polybutylene class action settlement to see if you qualify. The dates for most of the settlement relief is already past.
