2014年7月28日 · I'm having a new house built and the plumber just put in a parallel distribution PEX system. He put 3/8"s almost everywhere and I am trying to understand if it will be problematic. I have runs of up to 90ft, and an unknown rural city supply water pressure (60-70PSI?). The PEX design guide...

2008年7月31日 · I am doing some repeirs on a mobile home and the plumbing is the gray colored flexible type. I have been trying to learn more about this stuff. It is my understanding that the gray color indicates it is the older Qest brand that Shell stopped making. I need to …

2024年12月26日 · PEX-A is a solid choice for hot water systems. The expansion tool is necessary because PEX-A connections rely on expanding the tubing to insert the fitting. As the tube contracts, it creates a strong seal without needing crimp rings. Compression fittings are another option, but they’re not as secure as the expansion method.

2008年12月4日 · The i.d. for 1/2" pex is given as .475 inches (118 feet) with a fluid capacity of 0.0092 gal/ft (108 feet). I suppose the correct answer is that if you need something to measure a gallon of water with, don't use small diameter pex tubing

2015年1月9日 · I am replacing some rusted galvanized water lines vertical up through an interior wall. I was thinking of pulling a string down through the wall when I remove the old pipe then attaching the strings somehow to the PEX to help guide it through the previously drilled holes. I was wondering if...

2020年3月26日 · Pex b leak photographs are everywhere on the internet including the whole dezincification debacle related to Zurn and their pex b stuff. I think most of the leaks are because there can be too much variation in how a ring gets crimped.

2012年4月17日 · Is there a correct and accepted way to stub out PEX for supply lines to lav and WC? I had a house replumbed. The plumber transitioned from PEX to copper before going through the wall and to the valve. The stubout feels "floppy." Is this acceptable? Here in Ohio we're under the IPC...

2025年2月4日 · If your PEX pipe showed stress fractures and discoloration, it’s possible that high chlorine levels, UV exposure before installation, or pressure fluctuations contributed to its failure. Since PEX can degrade over time, especially with crimped fittings or poor installation practices, a full replacement is the safest long-term fix.

2011年12月7日 · Although radiant heat manifold and PEX tubing sizing are a different topic, let's assume, for example, that a manifold has 8 outlets with 1/2" PEX tubing installed at 300ft length per loop and the system calls for 72,000 BTU's. Using the formula above, we can determine the flow rate required for our given zone: 72,000 / 10,000 = 7.2 GPM.

2016年1月29日 · I used PEX B to replace most of my copper lines in the basement (which also fed the kitchen), and it was relatively easy to work with. I bought a few fittings locally, but online was so much cheaper for PEX and the fittings that I tried to put together a good list of supplies and make a couple large orders.
