Got a 2:12 a.m. call for a 1/2 inch copper split over a water heater; froze the line with a small can kit, pushed on a 1/2 SharkBite cap, and had the house water back on in 15 minutes. What’s your fastest reliable move for these after-hours bursts — ProPress, compression, or push-to-connect — when the goal is get them running now and return later for a proper fix?
At 2 a.m. I go ProPress on wet copper — cut back to clean, quick scotch-brite, then a 1/2" slip coupling or ball valve and I’m out in 10 minutes. Your “froze the line with a small can kit” works, but near a water heater I’ve had out-of-round stubs make SharkBites weep, so a compression cap is my backup.
I carry 1/2” ProPress stop-and-drain valves — instant isolate, then return; https://www.viega.us/en/products/systems/viega-propress.html. You add a union for cleanup?
Quick trick: slap a shop‑vac on the cold laundry faucet to pull a vacuum and stop the weep, then I ProPress a 1/2" slip coupling or stop‑and‑drain and have them back on in under 10; if the copper’s pitted or a little egged, I’ll throw a 1/2" compression cap and schedule a clean‑up. @sarah62 have you tried the vac pull instead of freezing?
