Your water heater is one of the hardest-working appliances in your home. When it starts acting up, you need a plumber who can diagnose the issue quickly and give you honest options. At P & D Plumbing, every water heater job is handled by a Master Licensed Plumber. We service all brands and types. traditional tank heaters, tankless systems, electric and gas. and carry most common parts so many repairs can be completed in a single visit.
Repair or replace?
Not every problem means a new unit. As a rule of thumb: if your heater is under 8 years old and the fix is a thermostat, element, thermocouple, or valve, a repair usually makes sense. If it's 10+ years old, leaking from the tank itself, or the repair runs more than half the cost of a new unit, replacement is the smarter money. We'll tell you which one you're looking at before any work starts, in writing.
