"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

It is okay to use a drain auger on a toilet, just make sure you are using the correct tip size. The auger is a plumbing snake with a protective sleeve to protect the porcelain toilet bowl from getting scratched. Using too large of an auger can cause the snake to loop back and damage the inside of the drain and plumbing.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

A liquid drain cleaner can sometimes make a clog worse over time if you use it improperly or too much. The chemicals in drain cleaners can corrode and damage pipes, causing cracks and leaks that may cause further blockages. If the clog is more than the liquid drain cleaner can handle, the cleaner will simply add chemicals to a bigger overall problem.

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.

If your washing machine drain is clogged, that isn’t a good sign. Unlike toilet drains or kitchen sink drains, there isn’t matter that is easily broken up with a plumbing snake, and more care is required. If you’re in an old house or have mineral-rich water, there could be a buildup inside the pipe. Either way, if the blockage isn’t obvious and doesn’t dislodge with a snake, you need to call a pro—otherwise, you risk damaging integral plumbing.
