How often should I check my plumbing?

Once a year is a good start, plus a quick look after any big storm or repair.

Should I flush my heater myself?

Many owners can, but ask us if you are unsure. Hard water may need it more often.

It is a safety valve on the water heater. It opens if pressure gets too high.
