Questions

How do I stop pipes freezing in Black Diamond?

Insulate pipes in crawl spaces and outside walls, drip faucets on the coldest nights, and know where your main shut-off is.

When should I replace old pipes?

Galvanized steel and polybutylene pipes are past their life in most homes — low pressure, rusty water or repeated leaks are the signs.

Is a leak an emergency?

Yes if water is spreading or near electrics — turn off the main and choose Emergency when you book; we call you at the first opening.
