Re-doing all supply in my remodel. Using pex a as recommended by many. It’s all completely in, used the professional Milwaukee expansion tool for all fittings. Now air pressure testing and using soapy water to find any leaks…I am getting small bubble builds in areas…these areas are on their second rebuild because they bubbled the first go around. This second time I used a heat gun to ensure a tight fit. I am at a loss since this is the second round and I am still seeing bubbles under pressure. I have asked a couple plumbing stores and professionals, they all have said to use water…I truly don’t want to cut and couple any more lines at this point…is the issue that I am using air and not water?

Oh, sad to hear you have some leaks. I've ran hundreds of kilometers of PEX-A from in-ground heating to water supply for homes and condos, so I know a thing or two about the system. The most common reasons why these fittings leak are the following; - Joint isn't inserted 100%. - Tool head isn't rotating properly. - Fittings are used or scratched. - On close joints, both sides need to be opened up before inserting fitting ( close joint) I suggest watching this video I made that gives out a lot of info on this system: Propress full guideIf you have any other questions just ask here, please post some pictures of the leaking joints if you can! |

Am I able to "heat off" the PEX from the plastic coupler fittings and try again, or should I re-cut? These were new out of the packaging fittings too
On your close join recommendation >> so for a shower valve with hammer arrestor you'd recommend opening both ends of a short run and placing fitting on at the same time?

I would restart the entire joint, if the head wasn't rotating for any reason the joint might get messed up again. As for the close joint, yes they need to be done both at the same time or the head will crack the adjacent fitting which will 100% leak. |

Will do, I guess my concern is MORE coupled joins in the line!
