"Matthew from Sila was amazing. Not only did he leave what was a mess, super clean, he put in the time necessary to help make sure that all the changes I wanted were in place. New PVC to the sewer line, new extra tap for the vent I'll need next year, re-routed old drains to not only look better, but everything is now tighter-knit and well-organized. Even threaded rods to bracket the drain and valve so that the whole system doesn't shake when it shuts off. I am thoroughly impressed with the focus, the time, and the result. Sila's pricing is high, but in this case I am convinced that I got what I paid for... a system that I won't have to worry about one bit, for many many years to come."

Sewer Cleaning questions, answered by experts

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.

If used correctly and sparingly, root killer shouldn’t damage your pipes. Make sure to follow the instructions on the back of the bottle or the company’s website to avoid any unintended damages. However, when it comes to copper sulfate, it’s better to avoid it. This type of root killer can damage your plumbing and the surrounding environment.

Roto-Rooter does not charge by the hour, so the quote you get after your in-person consultation should cover the whole project. This includes the time it takes a technician to get to your house and the time it takes to complete the job. For context, a plumber will charge anywhere from $45 to $200 per hour, but you may also pay a service fee or flat fee. 

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

Ejector pumps can only push sewage 750 feet or less. That’s because their purpose is to move waste from your home to your sewer line—which is a relatively short distance. Grinder pumps can transport sewage further, but they manage lower volumes of waste than ejector pumps (and they don’t work with septic systems).
