"Recently used Mahon Plumbing for various plumbing needs around my house. As a new homeowner you can be skeptical on what’s behind your walls or in this case pipes. Mahon did an initial sewer line inspection and called them back to swap out toilets and install natural gas in my backyard for a grill and fire table. They were professional, honest, and extremely knowledgeable about all phases of my projects. I would recommend Mahon Plumbing for all of your plumbing needs!"

"Tommy was professional and knowledgeable. He arrived at both appointments on time and got the valve and water heater replaced quickly. I would highly recommend them. I comparison shopped two other plumbing companies during the day and DB's was the best in knowledge and price."

"I live in a 57 year-old house, and it is not easy to find replacement parts.  They analyzed what was needed
and had no problem in repairing each item.  They also noticed that the toilet was not installed correctly, and
brought it to my attention.  What a difference it has made.  Great professional work by Brian and Juan.  I am so
pleased with the work performed and will continue using this company.

"My leaky toilet turned into a rotted sub-floor. The crew Reid sent over to replace the sub-floor/install a new one / install new tile was impeccable. Very professional and courteous. I would certainly hire them for other house projects or emergency jobs. Definitely the best in the area! Highly recommend."

"Charles heads up Ninja Plumbing and quickly answered the call for a clogged kitchen double sink. The root cause was accurately triaged to a backup on the main drain pipe where the two PVC drain pipes connected. With a declogging auger machine, Charles was able to unclog the main drain pipe drain running the full 50ft auger metal line and test the water successfully draining from half full sink of water all in under 60 minutes. Charles' ongoing interaction & communications during the full session of the fix was fairly reassuring versus other contractors who may mind more onlooking from customers for edification."

Toilets questions, answered by experts

The normal water level in a toilet bowl is about halfway full. The water should sit above the P trap drain because this creates a seal and suction. When you flush the toilet, the suction keeps sewer gases from entering your house through your toilet. Anytime the water level is higher or lower than half full, you need to make adjustments or replace broken parts.

The toilet flange anchors to the subfloor, usually with wood screws or cement screws, but most of it should sit above floor level at full height. When a flange is flush with the subfloor or below it, it can lead to the creation of leak paths.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

For best results, you should remove the toilet in a bathroom before removing tile or installing new tile. If you don’t remove the toilet, it will be harder to fully waterproof the tile around the toilet, which could increase the risk of mold growth or plumbing leaks. If you have trouble removing the toilet, hire a plumber to help.

The amount of water wasted when a toilet ghost flushes depends on the cause of the ghost flushing. Leaky flapper valves tend to waste less water than a larger problem like a damaged flush valve that makes the toilet run constantly. Even if you don’t think you’re wasting a lot of water, it’s still a problem that should be fixed quickly.
