"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

There are a few ways to unclog a toilet without a plunger. Break up the clog with homemade solutions containing soap, vinegar, and baking soda, or simply let hot water spend some time in the drain. You can also use a two-liter soda bottle filled with water to push pressurized water into the pipe to dislodge the debris (see the steps above).

Anything from debris, rust, ice, and even poor installation can cause clogs in your plumbing vents. Some signs of a clog include slow drains, gurgling sounds in drains and toilets, and bad odors. The bad odors are the most concerning, as these can include methane and hydrogen sulfide. Contact a plumber to come take a look if you notice any of these signs.

If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.

Regrading your yard can often fix drainage problems. You can also try aerating the lawn to encourage better drainage or install a new drainage system to prevent water from pooling in certain areas.
