"Called/texted at 11 am on a Sunday for a toilet valve leak. I could tell George was busy at the time, but he dropped everything to come to my home and do the job. His facility is approx 30 minutes away and he was at my home WITHIN THE HOUR. George was extremely professional, courteous, knowledgeable and reasonably priced. Am planning to have him return for a non-emergency to fix similar potential issues with the valves in my home."

"I had a clogged basement bathroom drain that another company was unable to fully resolve. I called 123 Sewer & Drain, and Mohamed came out on a Sunday morning. He accessed the line from the basement toilet flange and found multiple clogs that had not been fully cleared. What stood out was his thoroughness. He kept working until the line was fully cleared, then tested everything multiple times. He left the cleanout open and had me run all upstairs faucets and flush toilets to confirm that water was flowing properly to the sewer before wrapping up. Everything was done the right way — no shortcuts and no upselling, just a straightforward and professional approach. It’s refreshing to work with someone who takes the time to do the job right and makes sure everything is fully working before leaving. The issue has been completely resolved. I would absolutely use them again and highly recommend their services."

Toilets FAQs, answered by experts

Toilets typically connect to your main vent stack, a vertical pipe that runs through all finished levels of your home and exits through the roof. It’s located behind the walls, but if you have an unfinished basement or a utility closet, you may find a portion of it running the vertical length of the space. Some basement toilets use an air admittance valve instead, which is a small vent located in the wall directly behind the toilet that extends upward a few feet from the drain.

You definitely can over-tighten toilet tank bolts. Unlike some other materials, porcelain can’t bend or flex, so when you over-tighten a screw into it, it could break against the added pressure. Only tighten them as much as needed to keep them in place and firm; any more and you could risk breaking the porcelain.

While a leak may seem small, even a gentle trickle of consistent moisture can lead to mold problems in your bathroom. Make sure you know how to check for mold if your toilet has been leaking for a while. Pooling water by your toilet also poses a risk for someone slipping on the slick floor of your bathroom. Finally, a leak of any size can lead to water waste that increases your water bill.

In most cases, it’s better to repair a toilet than to replace it. Fixing issues like low water levels, running water, and flushing problems is less expensive than buying a new unit. Start thinking about replacement if the toilet is cracked, using excessive amounts of water, or is over 15 years old. Newer models are more water-efficient and clog less often than older models.

If your toilet won’t stop running, you might have a bad fill valve. This may be the case if the valve has calcium or debris buildup, is cracked, or shows visible signs of wear and tear. A bad fill valve may also be the culprit if you’ve already checked the flapper and chain and adjusted the fill height to no avail.
