"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!"

"Jeff was excellent from start to finish! Provided a lot of detail about the project and potential directions to go. His pricing was not the cheapest, but certainly was not highest in terms of quotes we had received. We went with him because he seemed honest and knowledgeable. We will definitely reach out for future plumbing projects."

"Chris G and John did an excellent job! DB’s Plumbing and Drain is an outstanding company. This job may seem a bit expensive but I ordered 2 higher end toilets and they had to deliver, install, and haul away old toilets. I have also hired them in the past to fix my water heater. All the technicians I’ve met are very professional and punctual! I will definitely hire for any future work!"

"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 FAQs, answered by experts

Yes, pressure-assist toilets leak, but less often than regular toilets. You might experience leaks from your toilet due to worn-out parts, water pressure in your plumbing that’s too high or low, poor installation, or cracks in your tank. These toilets are harder to fix on your own than gravity-fed ones, so it’s best to call a plumber if you can’t figure out what’s wrong, 

Yes, you can install a basement bathroom without breaking concrete by using an upflush toilet system, which includes a macerator pump. These systems sit on top of the concrete floor, so you don't have to drill into it to install plumbing. The macerator pump breaks up waste until it is soft enough to pass through a discharge pipe to the main sewage line. This method saves you time and money by bypassing the need to break concrete to connect drain pipes.

Yes, a toilet, sink, and shower can share the same vent. This is a common installation method that can simplify plumbing and save space. However, there are important considerations. The vent and associated plumbing must be large enough to handle the demands of all fixtures without compromising the vent's effectiveness. Additionally, the toilet should always be located downstream of all other fixtures. Because requirements can vary and space might be limited, it is essential to check your local building and plumbing codes and consult with a qualified plumber to ensure the installation is done correctly.

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.

Small bathroom renovation costs don’t have to break the bank. A $5,000 budget is realistic, provided you're not adding luxurious fittings or making complex layout changes. Changing the layout is the most costly aspect of renovating a bathroom. So if you keep the layout, do some of the job DIY (within your skillset), and use relatively affordable fixtures and accessories, you should be able to stay within your budget.
