"EXCELLENT! It was a somewhat emergency call because my walls were being damaged by the water, and Matt replied right away to my call trying to fit me in. He text back and said one of his guys, Ryan, was available and on his way! Ryan was great! Courteous, professional, punctual (and bonus - he unclogged the bathtub drain!). Thank you for saving the day!"

"Lane and his helper (sorry I can’t remember name) from Granite Plumbing removed a heating oil tank from basement that was over 1/4 full , drained tank and removed. Very professional, quick and careful. There clean up was immaculate. I appreciate that he was able to adapt to my schedule and come so quickly. I will be contacting Lane for future jobs. I would recommend Granite Plumbing. Thank you Lane"

French Drains FAQs, answered by experts

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

Drain fly problems can go away on their own—but only if the insects find the environment inhospitable. Those with a minor infestation can simply flush their toilets and run their faucets more frequently to flush out the flies and larvae. Others will have to deep clean their drains and set up traps.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

Most blockages can be cleared in 1-3 hours, but severe issues may take longer.

A plumber can get to the bottom of your smelly drain and clean it with specialized jets, hoses, and drain-safe cleaning solutions. It is also smart to call in a plumber if you suspect your drain smell is coming from a stubborn clog or even a leaky pipe.
