Exterior wall hose bib leak

Temperature went up to the 60's and plants needed water. Exterior wall hose bib (Arrowhead frost proof type) was opened with the 4 way splitter closed. I could hear water flowing. What's going on? Soon I saw water coming out of the weep holes.



I went inside and opened the drywall. A connector was sitting behind a 2x4 cross.

I put fingers around the connector but the connector and the fiberglass insulation were dry. Just no sign of wetness from this end.

I suppose the leak is somewhere on the long pipe of this frost free faucet and the remedy is to replace the whole faucet, not just the stem. As far as I could tell, the connection is threaded 3/4". I could not see individual threads but definitely not sweated. Am I in the right path? Thank you.

Sounds like it froze and split. You shouldn't leave hoses or splitters connected to a hose bib in freezing weather, since they hold water in the lines and completely defeat the purpose of having a frost free hose bib.

I am glad I posted the photo. Otherwise I would repeat the same mistake, leaving everything connected to the hose bib.

Most threaded spigots will be 1/2" NPT, not 3/4".

Repair update:
The faucet was 1/2" threaded indeed and failed exactly as you expected. The copper tubing ruptured lengthwise. Unfortunately I could not complete the repair. The same brand 4" faucet is about 1/2" too short. Next size is 6". Home Depot does not have an extension, only female and male fittings separately. If I solder them together, the faucet would stick out 1"+. Wife said no. I have no choice but to replace the ruptured tubing with the right length 3/4" copper. When I finally figured this out, it became dark.

Lesson learned: I should have hired a professional. The drywall didn't need to be cut open, since the pro would know the failure point and the right repair method. This forum is to blame in part, because without this forum I would have no one to ask and hired a professional 😁

I'm not following. How could you make any repair without opening the wall ?
The frost free bib was either screwed onto a 1/2" copper adapter fitting or was soldered directly to the pipe.

I watched a youtube posted by a pro. He shined a flashlight from the exterior and said it was threaded. I thought it would be that easy for a pro to tell the joining method.

Yes.... that would tell you if the valve was screwed into a fitting. However, spinning the valve off.... while hoping not to cause any damage and screwing the new one and hoping it's tight enough with no leaks is not like a pro.

Thank you PJmax. It is good to know I did the right thing (to cut open a dry wall). The hose bib was threaded into a female wall mount fastened to 2x4. The opening helped to visually verify no leak after repair.
