"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

You should not attempt to snake your sewer yourself. Accessing and snaking your sewer requires heavy-duty equipment, and while renting is possible, misusing it can damage your sewer main and leave you with very expensive repair costs, not to mention potential environmental issues and severe water damage. Accessing your sewer also exposes you to hazardous sewer gasses, and failing to seal the sewer properly after work can be very dangerous. It’s always best to hire a professional sewer cleaner near you to handle this type of work.

A good option for opening up and cleaning a sink drain is to use a ¼ cup of baking soda and 1 cup of white vinegar, along with a rubber stopper to cover the drain while those materials work their magic. After about 15 minutes, you can flush the drain with hot water. In many cases, these materials can scrub out minor clogs and get the drain working properly again. If the issue persists, call in a plumber near you to get the problem permanently fixed.

Although linear drains allow water to flow quickly and efficiently, they tend to clog more easily than traditional drains. Linear drains are flush with the shower floor, allowing soap scum and hair to potentially build up. They’re also longer than other drains, allowing for more space to let debris fall into the drainpipe. 

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.

Start by unscrewing the overflow valve, which is located on the wall of your tub between the floor drain and the tub spout. Gently insert a plumbing snake down into the pipe, move it back and forth, and pull it out. Remove any hair, debris, and soap scum that comes out with it. Repeat the process until the snake comes out clean, and then reinstall the cap on your overflow valve.
