"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

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups. 

The spin cycle on your washer should initiate draining, but if you still find leftover water in the washing machine tub, you may need to drain it manually. To manually drain a washing machine, you’ll need to turn off the power supply and locate the drain hose, filter, and pump. Open or disconnect these parts and let the water drain into a bucket.

There are a few reasons your snake won’t go down the floor drain. One common reason is a large obstruction in the drain that is causing a blockage. You can remove any debris you see in the drain before trying to snake it. In addition, the snake might not be long enough to reach the clog, or it might be the wrong diameter. 

A saturated leach field can result from various underlying issues, so it's best to call a professional septic company to diagnose and treat the problem. Depending on the cause of the saturation, potential fixes include pumping out a full septic tank, adding more bacteria to the tank, or regrading the soil to fix low spots. It may also be necessary to reroute rainwater and runoff away from the leach field using gutters, downspouts, and extenders. Once the primary issue is resolved, planting specific types of vegetation over the area can help absorb excess water. In more severe cases, you might need to install a larger septic tank or replace the leach field entirely.

It is generally not recommended to pour hot or boiling water down a drain to unfreeze pipes due to significant risks. In some cases, the sudden temperature change can cause more ice buildup or produce steam, which increases pressure and could cause the pipe to burst, leading to costly damage and potential burn injuries. While hot water might help with a partially frozen drainpipe, it is unlikely to thaw a completely blocked water pipe further down the system. Additionally, boiling water can damage plastic pipes over time. Safer and more effective methods include using a space heater near the frozen section or applying hot towels directly to the pipe.
