Good to know

Plumber questions, answered

When is a plumbing problem an emergency?

Water you cannot shut off, sewage backing up, a gas smell or no water at all. Shut the main valve, then call. Everything else can usually wait for a regular appointment.

How often should a water heater be replaced?

Tank water heaters last about 8 to 12 years. Tankless units can last 20 or more with annual flushing.

Should I use a drain cleaner before calling?

Chemical cleaners can damage pipes and seals. A plunger or a hand auger is safer. If a drain clogs repeatedly, there is a deeper problem a plumber should look at.
