"Gage has been excellent to work with. We will hire him any time we need something in the future. The work site is always clean, the new install always looks tidy. He has installed a water filter, fixed several leaks in old plumbing, replaced hose bibs, worked on our booster and expansion tank, replaced fixtures. It's always great work."

"Eric was right on point and identified the solution and scope of work very promptly. He is a very good communicator via text and in person. I thought his pricing was very fair. He worked to install gutter on my roof, drainage piping, and a trench drain on the side of my driveway to mitigate erosion. He rototilled, fertilized, and installed sod on my formerly eroded front lawn. The work came out fantastic and my neighbors keep complementing me on how nice my house looks now."

Customers say: Quick response

"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

"When our existing water tank started to falter we knew we needed to upgrade. Derry Plumbing and Heating installed a phenomenal tankless system for our 3800+ sq foot home and we never had a reason to complain. Our energy costs went down and we always had hot water for our family of 5 and numerous guests."

Drain Pipe Installation FAQs, answered by experts

A small amount of diluted bleach is okay to pour down a garbage disposal. As part of your weekly garbage disposal maintenance, use 1 teaspoon of bleach with your concoction of ice cubes and lemon peels. Turn on the disposal and run the water until the blades chop up the ice cubes.

Any more bleach in your disposal can harden oils and greases in your drain, which can cause problems. Always wear gloves when working with bleach, and know that you really don’t need bleach at all—vinegar, baking soda, salt, and ice should do the trick.

If the drain pump on your washing machine is continuously draining, it could be that the control board is damaged and requires repair, or there’s a clogged or kinked drain hose. If you can’t locate the problem, you’ll want to have a plumber or appliance repair expert come take a look.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

Simple blockages can be cleared using household plungers or manual snakes, provided no severe plumbing issues exist.
