-
What’s the difference between a drain and a sewer line?
Your sewer line refers to the main pipe into which all of your drains feed, the pipe that carries waste water away from your home to the municipal sewer system or your septic tank. A problem affecting a drain may only affect one drain or only affect drains that are “upstream” of the clog, while a sewer line issue will affect every drain in your home.
-
Can I install an electric water heater myself?
For safety and warranty purposes, it’s best to have it installed by a professional like Donley A/C & Plumbing.
-
Is it safe to use drain cleaner when I have a clog?
While drain cleaners can quickly fix slow drains, they often contain harsh chemicals that can damage your pipes over time. A mixture of vinegar and baking soda or a plumber’s snake can be a safer alternative for minor clogs. For persistent issues, it’s best to consult a plumber.
-
How often should I get my electric water heater serviced?
We recommend annual servicing to maintain top performance and longevity.
-
What should I do if a pipe bursts?
First, shut off the water. From there, clean any standing water and air out the area with fans, if necessary, to prevent water damage. Then, call our team as soon as possible to schedule a plumbing repair.
