"Thank you to Geremi and GMC plumbing for all your hard work. They replaced all my pipes, my tub, toilets, faucets and fixtures, my hot water heater and the casing that houses it and they re-dug the sewer line. All this for a very reasonable price and they could not have been any more courteous and professional. Highly recommend this licensed plumber for any project that you have."

"The problem was the toilet. They hydro Jett the main sewer line , using a camera to demonstrate where roots were. Afterwards , the toilet flushing was still as slow as it ever was. Better support would have been to suggest YouTube video titled unbelievable Trick to Make Your Toilet Flush Like Never Before! On jayâ s How To Channel which showed how to remove calcium & lime deposits Fromm the jets of my toilet using extra strength vinegar poured many times down the overflow spout Iâ m the tank. They didnâ t even bother to check out the toilet until AFTER the sewer line Hydro-jet."

"Had a problem with a toilet flange and installing an Swedish toilet. Swedish toilets are going to be the next big thing. But the supply line feed is on the other side of the toilet and the supporting flange can't be from the 1920's. Dynamite plumbing got it done the same day. Literally perfect."

"Samuel is my go-to call for all plumbing-related projects, small and large. He's supremely professional in his approach, and is sure to communicate all costs, timelines and potential issues that may arise during a project. When he's had to bring in a team for drywall, painting, etc... they've all been extremely competent, as well. Strong recommendation."

"Man. What can I say? I am always cautious of any service but boy was I happy with Leon Plumbing. My tankless heater was leaking on a Sunday. A small leak that a bucket could handle. I called 3 places recommended by Rinnai and out of those 3 only Leon?s picked up. I told him it was not an emergency and if he could come asap. He scheduled me for Monday at noon. Omar came and boy was he a pro. Within 5 minutes he knew the issue. I could have been ripped off for the fix but their prices were extremely fair. I saved their number as a permanent contact for future service and repairs. I won?t even bother with other quotes. Once you trust you trust and I trust Leon?s Plumbing."

Toilets FAQs, answered by experts

Yes, an ambitious homeowner could decide to replace their own toilet. A person attempting to do a DIY toilet installation should keep in mind that the average toilet weighs between 100 and 120 pounds. That means that you'll need to be comfortable lifting and carrying your old toilet and replacement toilet during both phases of the project. Additionally, homeowners will need to have basic plumbing knowledge to avoid plumbing problems that could result in messy, expensive water damage in their bathrooms. Hiring a plumbing pro from the get-go can help you avoid damaging your plumbing or your new toilet.

Your toilet handle might not come back up if the nut is loose or the bolt threads are stripped. Try to tighten the mounting nut and wrap plumber’s tape around the handle bolt to fix stripped threads. It’s possible the handle was improperly installed. If that’s the case, you can use the instructions above to correct the handle’s position. 

Yes, you’ll need to replace your toilet’s wax seal any time you move the toilet. This is because movement of the toilet will break the seal, rendering the remaining wax useless. Thankfully, replacing a wax seal is fairly easy, and the seal itself only costs $2 to $10 at most home improvement stores.

When replacing a wax seal you typically also have to replace the closet bolts that secure the toilet to the flange. These are usually about 2.5" - 3" long and have to be cut once the toilet is secure. Cutting them usually makes them too short to reuse.

Toilet handles can get stuck for a couple of reasons, but it’s commonly an issue with the chain. Remove the lid and check the chain’s connection, running from the flapper to the handle arm. Sometimes the chain gets snagged on or against another part of the tank. 

The chain might not have the right tension. For example, a chain that’s too short can make the handle feel stuck. Check that there’s some slack in the chain. Old, worn-out flappers can get stuck, too. In this case, you’ll need to see which size toilet flapper you need.

Yes, you can clean a toilet tank with white vinegar. Before you do, shut off the water supply to the toilet. Then, flush it to empty the tank. Next, combine one part vinegar with one part water in a spray bottle and spray the mixture inside the tank. Let it sit for 10 minutes, then rinse away the vinegar by pouring clean water into the tank. Make sure the tank is empty, then dip a scrub brush in vinegar and clean the tank’s inside walls. Turn the water back on and flush again to rinse away the vinegar.
