"Pedro and Caesar were two of the very best people I have ever hired. They worked tirelessly from the moment they got here to when they finally went home in the late afternoon. They didn't take any breaks except for a short lunch. They were very patient in answering all my many questions, and the thing that amazed me was their complete and total good cheer: they never grumbled, or even let out a sigh of exasperation, and they had a couple of very difficult parts that took a couple of hours each to just get new pipes into very tight spaces. When I asked if it was very difficult they just cheerfully answered that "oh it's just the way it goes." Pedro had to return a couple of times to trouble-shoot a leaking toilet and he did so very patiently. Their work was excellent and I would re-hire them immediately. I also very much appreciated Martina's clear, and super friendly help each time I called."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"I hired Ray to come and install a new toilet in my guest bathroom. He was very professional and arrived on time and ready to get started. He is very knowledgeable and was able to suggest a different option then what I originally wanted. His years of experience saved me time and money by having the job done correctly and with the right toilet for the space available. I would recommend Ray to all my friends and family who own their own homes."

"The worker fixed the Toto toilet, installing all the factory replacement parts I supplied, and everything if fine now, a much better situation than having to get a whole new toilet. Also I probably could have done the job but if it did not work Id catch hell after, and Im not a plumber. As a plus he tightened the kitchen faucet which had become loose, spending a bit of time on it and not charging for it. Would recommend and use them again."

Toilets FAQs, answered by experts

Yes, you can have a toilet without a septic tank. However, it will have to be a composting toilet. Composting toilets work similarly to aerobic septic systems in that the waste, which sits in a separate compartment below the toilet itself, is slowly broken down by aerobic bacteria. These toilets typically have a vent to get rid of harmful gasses with a fan, which requires a battery. You will have to dispose of waste in the toilet manually every three weeks to every three months, depending on how many people are using the toilet.

Adding another bathroom isn’t the most complicated project you can undertake, but it’s in the top 5%. Anything involving plumbing and electrical work should be handed off to a pro, and adding a half bath involves both. A contractor may charge $70 to $120 an hour for labor, but chances are they can work much faster and more accurately than a DIYer.

The most common reasons a toilet won’t stop running are a faulty flapper or fill valve, improper fill height, or incorrect chain length. Luckily, all these issues are relatively easy to fix with parts you can find at a local hardware store. You can also call a plumber or toilet repair professional to solve the problem.

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.

If you have to hold the toilet handle (also called the toilet lever) down to flush, you probably have a chain problem. A chain that cannot fully lift the flapper will close too early and not clear the toilet bowl. Try adjusting the chain length so there’s about ½ inch of slack.
