William Thomas Plumbing
Company Overview
High-pressure drain cleaning, drain cleaning, tankless water heaters along with temperature control systems, covering all types of plumbing for restaurants and business facilities. Furthermore, we repair as well as install grease interceptors and separation systems.
Our journey began by hydro jetting as well as drain cleaning. Initially, we stood out as the sole provider in the area focused on grease management systems for restaurants. We operated the first high-pressure jetting system that we used to clear grease-laden pipes. This equipment was known as the Mustang and served us well for many years after acquired our first mobile jetting unit which was a US Jetter. Our team started installing commercial grease traps as well as smaller grease traps.
The owner, Bill established this business back in 1980. As an independent plumber, I can take on small-scale jobs as well as larger commercial projects with the same work ethic. I make time to dedicate the right amount of time to do the jobs thoroughly.
I’m just starting out on YELP, but our company boasts gyms, dining venues and homeowner testimonials from Long Beach and nearby communities and the local vicinity.

Recommended Customer Reviews

I had a wall pipe clog which was beyond my novice skills for fixing. After reaching out several other plumbing companies and talking to some of friends I was recommended to Bill by one of my friends for his good work and reasonable pricing. I called him, where he gave me the best quote. He drove down to Tustin even though he's based in Long Beach, fixed my clog issue and provided me with a bunch of general pipe care tips during his visit. He's was very polite and I appreciate his hard work & dedication to his work.

We have used Bill's services off and on as needed for over a year now, from plumbing issues, gas line issues, and water heater install. He's always dependable and quick to respond. He works weekends and has answered our needs on holidays even. We continue to rely on him. Prices are fair and reasonable. Very professional. Very courteous!

We have had great experiences with Mr. Thomas aka Bill the plumber! He was courteous, efficient, and pleasant to deal with. We hired him to fix 2 bathroom toilets in both of our homes, and shower head. He arrived in a timely manner, assessed the problems, ordered the parts from Kohler, then fixed the toilets as soon as they arrived. He even adjusted the toilet pump to be water efficient to save on our water bill! This is our second time using Mr. Thomas' plumbing services and we strongly recommend him for any plumbing issues you have!

Had water leak in front of my house and bill did a great job on it. I'd recommend him recommend him if anybody has pluming issue. He's prompt and his price is fair.

Our main water line was rusted and sprung a leak so we reached out to a few plumbers and chose Bill! He was awesome! He told us his plans to fix the problem and explained why. He dug a trench to lower our main line and put in copper piping. He was trustworthy, sincere, personable, performed excellent work, and had great pricing! He was a great communicator and got the work done fast! We will always call Bill when we need work in the future. Thanks again!!

First thing first Bill here is an amazing man and gets the job done! It was Christmas eve a couple of days ago me and my girlfriend were cleaning up our house for Christmas day festivities with family and friends. Just so happens our pipe in the bathroom suddenly exploded sending water gushing everywhere (A scene out of the movies). We both panic! Running around like chickens with our heads cut off! We're both trying to find a way to make the water stop. I finally find the main water valve (about 20 mins later) by then the bathroom is flooded and water is everywhere. We called plumbers none of whom could make the call.(Christmas eve) We flag down Bill here because he stays several houses down from us. We caught him just as he's leaving for Christmas eve dinner with his family. He puts his plans on hold and comes to our house and temporarily fixes it. Tells us he'll be back in a couple of days. He made good on his promise came back fixed everything like he said. Fast and efficient! Great pricing as well! This man works miracles! He's a miracle man! THIS IS MR. GO TO! HIGHLY RECOMMENDED! if you're reading this Bill you are the MAN! Thank you for your services!

We are a small sized restaurant who have been greatly helped by Mr. Thomas. We have worked with Mr. Thomas on 3 different occasions.
1st Time using William Thomas Plumbing; We had an emergency stoppage due to a major clog from the use of metal fiber sponges in the main line. Busy Saturday night of conducting business when we realize that the plumbing is starting to back up. We instantly go online to look up plumbers in the area. The majority of the plumbers that answered where trying to charge me a ridiculous amount of money for a jetter service and we would have to wait until the next day in order for them to come. Luckily we found William Thomas Plumbing, I spoke with Mr. Thomas and he was there within the hour! Not only did he come over ASAP, his charge for the same ""emergency"" service was his standard rate! Mr. Thomas did not use our unfortunate situation in order to over charge us for essentially the same service. Mr. Thomas did a great job, works very cleanly and quickly.
2nd Time using William Thomas Plumbing; Our mop sink became clogged with blackish color water. Having used William Thomas Plumbing prior to this we booked him to fix our issue. Mr. Thomas needed to break concrete to replace broken pipe that was underneath concrete. Mr. Thomas worked around our business hours, working through the night while leaving the place clean, covered and ready for us to be able to work throughout the day. We did not have to close! Mr. Thomas fixed our mop sink problem and sealed up the floor all the while charging us a reasonable rate.
3rd TIme using William Thomas Plumbing; We referred William Thomas Plumbing to our sister company La Fiesta Meat Market. They had a problem with the sink drain in the bakery. Mr. Thomas was quickly able to figure out that there was something majorly wrong in the way the plumbing system was built. The original plumbers who built the plumbing system installed a T-fitting in the opposite manner than should have. Mr. Thomas fixed the problem and installed cut outs so that if ever be we could snake through there as opposed to removing the sink.
Luckily for us we have found William Thomas Plumbing. We have used their services in case of emergency and did not have to pay emergency pricing. If you have any plumbing issues I suggest using William Thomas Plumbing services, especially if you are a business as other plumbers often over charge businesses for similar work just because we are a business!

I strongly recommend Bill for your plumbing projects. When you call Bill, you can be assured of the following - Realistic service window, honest pricing without unnecessary up-selling, and a check-in the next day to see if things are working properly. I got into a project (faucet replacement) that went a bit beyond my comfort zone. It resulted in having to shut the water off to my house until it was resolved. This was on a Sunday. Bill went out of his way to get to me ASAP so I could restore water to my home. Additionally, I thought the problem was bigger, but Bill didn't try to sell me stuff and services I didn't need.
Clean, friendly, timely, knowledgeable, honest... You don't need to look any further. Call him.

Bill is a hard working, slow, diligent, plumber. We had some problems with our plumbing with a clog in our main line and he responded immediately. He worked long hours and fixed the problem. He was also friendly and clean while working in the house! He also explained why we were having problems and gave us ideas/solutions for how to prevent further complications and problems.

I found Bill on a school job we were working on a few years ago and just happened to find his number again so I called and left him a message and sure enough he called me back.
We had to run a new 1-1/4"" gas line to a large heater, Bill was very professional and reasonable. I referred him to a property management company to and they just love him. Thanks for the great service Bill
