Need a little bit of help have a house with blue plumbing coming out of the slab. Looked all over but there is no lettering what so ever to give me any indication one way or another if its PB or pex. Looked through attic and other location the rest is copper. Anyone know if its pex or pb or know of a way to test it? The fitting doesn’t look like the standard fitting for PB not sure.
Identification
The most effective way of identifying polybutylene pipe is to have your plumbing inspected by a licensed professional. While inspectors generally cannot determine if there is deterioration in poly piping, licensed plumbers can confirm if you have poly piping installed in your home. Typical characteristics of polubutylene piping include:
[LIST]
Blue, gray, or black color
½" to 1" diameter
[/LIST]Poly piping can be used anywhere in the home’s plumbing system – usually its presence can be ascertained by checking the attachments under household sinks, near hot water heaters, or leading into toilets. Following is a list of common places you may inspect for the presence of poly piping:
**Interior
[LIST]**
Entering the water heater
Crossing basement ceilings
Feeding sinks, toilets, and bathtubs
[/LIST]**Exterior
[LIST]**
Entering the home through basement walls, etc
Attached to your home’s main water shutoff valve
Attached to your home’s water meter (often a copper pipe at a water meter will be attached to poly pipe somewhere underground, so it is wise to check both ends of the pipe)
Factory built main water line not a make shift poly or pex. At least that is what I see in the picture.
Here is the right up now that I am back in the office.
PE (Polyethylene) plastic is black or bluish flexible pipe sometimes used for main water lines as well as irrigation systems.
Now to further add to this it can be purchased with the threaded end female or male to connect to the copper lines. In most cases the fitting is stamped with the info written on it and the pipe has nothing. I am not saying it is PB, PE or PEX without seeing the writing on the union.
The manufacturer of the union is MCD and is ANSI approved. http://www.truesdail.com/specialty_testing/listings/aymcdonald.html
