Emergency Plumbing Supplies to Keep at Home

What to keep on hand so a plumbing problem stays small until a professional arrives.

The first two minutes matter most

Knowing where the main shut-off is and having the key or wrench to operate it limits damage more than anything else you can buy. Fixture shut-offs under sinks and behind toilets let you isolate a single problem without cutting water to the house.

A short, useful kit

Separate sink and toilet plungers, a bucket and towels, thread-sealing tape, a basic adjustable wrench and a torch. That is enough to contain most household plumbing incidents.

Avoid chemical drain cleaners

They can damage older pipework common in this area and make the eventual professional repair harder and more expensive.

Call a licensed plumber for these

Sewage backing up, no water at all, a failing water heater, gas smells, burst supply lines, repiping and anything behind a wall. Shut the water off, then request a Pro Match.
