"I was contacted by two plumbers. The first wanted me to find the part on my own, then maybe they could fix the toilet. Wilmar came out the same day, called the supplier from my house and came back the next day with the right part. Quick, friendly and I will call him again if I need a plumber1"

"Let me say that Gustavo was great! Professional and kept me informed the whole step of the way. Pricing was up front and no surprises. He ended up having to replace the toilet flange on the toilet on the second floor. AND he repaired a small section of the ceiling on the first floor due to water damage. All within one day. He and his assistants were very good."

"I met Gert when we hired him to replace our Tankless water heater. I was so impressed with is knowledge and concern to make sure the installation was neat and clean. The piping is literally a work of art. We met with Gert and Sergio to discuss the next phase. They removed all the galvanized pipe and installed 3/4" copper with a true hot water recirculating line for Tankless recirculating pump. Before they started work, they came in and placed protective covers over the hardwood floors. Sergio and his team replaced all the cast iron drains with ABS. They even opened walls where needed to get to the old galvanized drains to the sinks. They pulled up toilets and replaced the old flanges with new ones. All that's left is the sewer line from the house to the street. We will be calling Gert and Sergio when reach that point. Gert, Sergio and the whole crew have something you do not see that often anymore. That's integrity and concern for their customer. Also very conscientious of keeping our home clean."

"We had a leaking toilet. Jose Romero of Core Plumbing responded to our request on Angi within ten minutes, and arrived at our home within twenty minutes. The problem turned out to be much more serious. The drain pipe beneath the toilet was clearly cracked and needed to be replaced. This is an older house, and there was no surprise here. Moreover, the pipe was in a narrow crawl space. Mr. Romero assessed the situation, provided a reasonable quote, and we authorized the repair. He came with his colleague Freddie the next day and did a thoroughly professional job, installing the new floor drain pipe, a new floor fitting for the toilet including a new concrete collar, and a replacement toilet all in one day. He was scrupulously clean, efficient, and we were amazed that he could accomplish this in a single day. We were very impressed with the work, and found him and his colleague straightforward, informative and pleasant. We would hire him again with pleasure. Highly recommended."

"Jess was on time and kept me informed with all the work he was doing. He was professional and courteous. He gave me an estimate and stuck to it, even though he had to work a lot harder than he thought to replace the broken toilet flange. I will definitely use him again and recommend him to family and friends."

"We've been working with Mike Counsil for over 8 years - clogged drains, water heater, new toilets, and most recently a sewer re-pipe. Yes, they may be more expensive than other companies, but with Mike Counsil you get what you pay for - quality work. A big shout out to Rudy and the whole team - they are hardworking, reliable and courteous."

Toilets FAQs, answered by experts

While gasket-sealed PVC flanges are the type most commonly found in homes, flanges come in a range of different materials, including copper, brass, stainless steel, cast iron, and aluminum, that pros sometimes secure with glue. If this is the case in your bathroom, the replacement is a job better left to the pros.

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.

Completing a full standard bathroom remodel offers the best value, with an average return on investment (ROI) of 70%. However, you don't need a full remodel to make an impact. To maximize value, focus on key components like flooring, the tub and shower, vanity, and cabinets. High-value upgrades include installing a walk-in shower, resurfacing a tub, retiling, or expanding the shower. For more budget-friendly options that still increase value, consider repainting with a light, neutral color, or updating the mirror and light fixtures. It's also crucial to address any necessary repairs, such as leaks, mold, or cracked tiles, as buyers will notice these issues. Avoid flashy upgrades like bathtub jets or steam showers, which don't add as much value.

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.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor.
