"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

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

There are many issues that can cause cold showers, but the most likely is a problem with your water heater, especially if other fixtures also don’t get hot water. If it’s just your shower not getting hot water, you likely have a broken or damaged shower cartridge. You can replace this yourself or hire a plumber to do the work for you if you’re not comfortable working with plumbing.

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.
