How far apart should PEX tubing?
PEX tubing is usually installed within a distance of 8". Closer spacing (usually no less than 4") can be applied to areas with higher heat loss or floors with lower heat conductivity. Length of each tubing loop - The length of a tubing loop is directly correlated to the flow rate and heat output.Can you use PEX for sprinklers?
Cross-linked polyethylene, or PEX, pipe is another product making its way into the irrigation industry. It has a higher burst pressure, which is great for high-pressure mainlines, Stryker says, and PEX can withstand freezing temperatures so it can be used in any environment.How often should PEX be supported?
