"Ambassador Plumbing was my first choice and the only one of three companies to respond to my request for a quote. Paul came within a couple of weeks and did a fine job of replacing my Mansfield toilet with their recommended Kohler one that met my specifications. I'm very pleased with not just the toilet but the work too. (Note: Ambassador does not honor the Angi 5% coupon displayed on their site.)"

"Absolute best. I had three bids. One was way over the top. The other bid was slightly lower than the one from Maplewood Plumbing, but they stopped responding to my questions after I asked them two times. I understand that if it was just a $200 job, then it would not be worth the time, but $2,500 was no chump change. Couldn't I ask just a couple more questions to make sure I knew what I was getting into? Maplewood plumbing was different, from start to finish. They even came out a second time to take a closer look to reassure me on what needed to be moved or removed first in order to start their work. I doubt many companies would want to do that. The plumbers working on the job were happy to answer questions as well. There was a small drip in the water supply line/shutoff valve area of the toilet after they were done with the job, They fixed it after a call. Some companies just leave these loose ends unfixed, but they didn't. The office staff was also responsive and professional. All in all, they were such a pleasure to work with. Will definitely hire them for future plumbing needs."

"Could not have been better. Ran into a scheduling issue with another plumber. Called Kirkwood Plumbing on Monday, they were able to schedule us for the next day. Gave them the info from the original plumber's proposal and they agreed to match the cost and work. Plumber was running late due to very heavy traffic. Called 45 minutes before the scheduled appointment to let us know he might be a little late. Arrived only 10 to 15 minutes late, which was fine with us since he had called. Got right to work and finished within a few hours."

Toilets FAQs, answered by experts

While you shouldn’t increase the flow of your low-flow toilet by adjusting the water level in the toilet bowl set by the manufacturer, you can make the flow as efficient as possible by ensuring the rim jets under the rim are unobstructed. To do this, use a mirror to look under the rim and scrub them with a toothbrush or a small wire to clear any debris stuck in the holes. You can also watch for leaks, make sure the internal components are in good shape, and replace them if necessary.

First, check that you have cut off the water supply to your toilet. This is a project that can only be done safely if running water cannot reach your toilet fixture. If you're seeing water trickle out after you've confirmed that the water supply is shut off, you can probably rest assured that what you're seeing isn't a problem. It's common for leftover water to spill out when you're removing your toilet's fill valve. If something goes wrong while you're working on your toilet, you'll need to look at your home's policy to see if your homeowner insurance covers water damage.

Sometimes, your insurance policy may cover leaking toilet repair. However, home insurance policies typically do not cover any plumbing problems. They do cover water damage caused by a busted pipe or a major leak. Some insurance companies also have riders that expand your initial coverage to include plumbing items. Talk to your agent for more information.

Silicone-based caulk is known for its waterproofing qualities, so it’s the best option for any bathroom area. While it’s often more expensive, it will provide a better, longer-lasting seal than acrylic or latex caulk. Use it along the base of the toilet to prevent leaks and keep the area clean and protected.

Many parts of your plumbing system can fail, but clogged drains are one of the biggest plumbing problems you’ll likely encounter. From your kitchen sink, bathroom sink, or bathtub, there are plenty of opportunities for gunk, hair, food scraps, and more to get stuck in drains. When this happens, water will slowly drain, leading to standing water, bad odors, drain flies, and other issues.

Many homeowners can handle a minor clog themselves, but if you have a clog in your main line, you’re best off hiring a local plumber to get the drain back to its normal flow rate.
