"David called me within 10 min. of posting the request, & enquired details and gave me a quote for the annual maintenance. His quote was very reasonable, and was upfront about what is covered and what was not. He was on time, wore booties w/o asking (I am particular as we have a toddler), finished his job thoroughly & patiently answered every question I had. I had couple of other minor issues - he fixed those w/o any additional charge! He checked my water heater too, for no additional charge! He didn't oversell, and came across as genuine, and someone knowledgeable."

"I was thoroughly pleased with the installation of my new kitchen faucet. What I liked is that they went above and beyond. There were other things in the house that needed attention and Kyle changed did a "wellness" check around the house, the bathrooms and found that the faucet to the outside of the house needed updating. I wills say that their price was a little high but for my peace of mind, it was worth it. Within 5 days of my work being done, I recommended them to a co-worker who needed a hot water heater repaired and they are satisfied with that work too. Yes, I will call on InstaPlumbing again."

"P&M Plumbing arrived promptly and on short notice. The work was done very professionally, area left clean and orderly and the sump pump works phenomenally! I had spent 17 hours vacuuming and lugging water after the last storm, so I was thrilled at the thought of having a sump pump. We received about 3 inches of rain the next day and they even called to make sure everything was working well! In this day, it is a wonderful surprise to have a company really care about the customer and the quality of their work and I am more than delighted. Even with the 5-6 inches we received last night, I had no cleanup to do! I am highly recommending P&M!"

Water Heaters FAQs, answered by experts

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

If your water heater continues to have issues, you may wonder how long an electric water heat lasts. On average, these units last between 10 to 15 years. Following a proper maintenance schedule can help the water heater live to the end of its average lifespan or longer.
