Showing how to install a new hose bibb with a PEX maintenance loop. Installing a PEX expansion loop can be added to a replacement hose bibb as well, with enough open space around the current location. Requirement #1: Location is key when it comes to installing an expansion maintenance loop. It has to be within a wall. Specifically, where a wall is perpendicular to an exterior wall. Requirement #2: The loop has to have space to expand and contract as well as extend into a significant amount of space. So it takes up an entire bay within a framed wall. *One lesson learned is we should have run the 3/4" PEX line all the way through the loop to maintain higher pressure. Next time. It also means the PVC sleeve needs to go from 1-1/2" to 2" for the enlarged PEX. At the time of this install we were unaware of the Uponor 3/4" to 1/2" sweat copper to 1/2" female NPT connector. **It still is a good idea to have a shutoff to the hose bibb within the line. If you have a trunk and branch system, a “stop and waste” ball valve (with an access panel if needed) is good plumbing practice. These photos are on a water manifold with home runs to each faucet, but it is still a shutoff where the spigot can be opened and water drained. Perhaps a massive amount of waste in comparison to a shutoff right there, but it is comparable to flushing a toilet and you only turn it off so often. ***If this is in a house where winterizing is necessary, the lines will need to get blown out so that water is not left in the loop. MATERIALS REQUIRED: ○ PEX (we're partial to Uponor's PEX-a and here's why: https://www.justneedspaint.com/reasons-to-choose-an-uponor-manifold-system/) ○ PVC cleanout ○ PVC elbow ○ PVC pipe ○ PVC primer/ cement ○ PEX talon clips ○ Hose bibb (you've got the space if you can include a loop so ideally a frost-free one.
