In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch. Remember that water pressure decreases by a half-pound per square inch for every foot pipes extend above your water supply.2021-01-21
Can you expand PEX too much?
Temperatures also affect the number of expansions needed for a fitting. In cold conditions, you need to be careful to not over-expand the pipe, because over-expanded pipe takes longer to contract in cold conditions. However, a heat gun or hair dryer will fix leaks caused by over-expansion in cold conditions.2016-09-21
Do PEX fittings reduce flow?
At a rate of 8 feet per second, the CPVC fitting will cause less than 1% restriction in flow while PEX fittings create a 23% to 54% reduction in flow, depending on the fitting used.2020-01-21
Why do my expansion PEX fittings leak?
As with any other pipes, PEX is not prone to leaking. Nearly all of the plumbing leaks occur at joints (connection spots) and most of them are due to incorrect installation. Much like installing PEX tubing, repairing it is also an easy process.
How do I know if I have PEX A vs PEX B?
Again, the main distinction lies in the manufacturing method, which is what assigns an A, B or C to PEX. PEX A is made using the Peroxide, or Engel, method. PEX B is formed using Silane, or Moisture Cure, method. This is the most common PEX pipe type out there.2020-11-06
