I developed my work ethic at a young age, cleaning tables and helping customers in my grandparents' restaurant. I continued this until I was 16, and at 12, I delivered newspapers for a couple of years. I spent my summer vacations at 13 and 14 working in my uncle's welding shop. I started as my father's plumbing apprentice and soon moved to Riverside to work in residential new construction.
I attended a year-long plumbing program at Associated Tech College in San Bernardino, focusing on plumbing codes, repairs, and sizing systems. After that, I joined Inland Plumbing as an apprentice, and within a year, I was promoted to foreman. In that role, I installed gas systems, drainage, venting, and water services, managing three team members. I learned extensively during those three years, and I feel that was where my plumbing foundation was established.

Recommended Customer Reviews

Juan came through at the last minute for my husband and I regarding our toilet dripping water from the pipe behind the toilet, the toilet pressure and our sink was smelling weird haha. He was super fast in and out in about an hour and fixed both issues and was extremely personable and friendly. We enjoyed the short time with him! He was knowledgeable as well and the company responded very fast to helping us out. Definitely would use them in the future for sure.

Very fast service, punctual which is great...no huge time span of when they would arrive. Said 8:30am and literally on the dot showed up. Fixed a main line back up, in no time at all. Was done within an hour or a little less. Very professional. I recommend NIR for plumbing needs.

Fast, efficient, and affordable. Mike and Ricardo came out within 30 minutes of initial call and fixed the problem right away. They were personable and knew what they were doing. I highly recommend them.

Our toilet got backed up on a Sunday afternoon but I got a quick response. Sergio came out Monday morning, worked fast & was able to fix our toilet in no time!
Me & my housemates are thankful!!

Nick is amazing. Came to a house I have in Corona and fixed the entire list I had including things like: water pressure and water heater issues. His advice is unparalleled and he is extremely courteous. I would recommend to everyone in a second!

NIR is by far the most professional plumbing company available. They do great work which is the most important factor in terms of quality. Their work makes them a top notch brand. I would highly recommend them without reservation.

What a relief when a friend recommended NIR Plumbing. We had a clogged drain and called in the morning and a few hours later it was fixed and the price was reasonable for all the work they did to unclog it. Our plumber was professional and personable. I too would recommend NIR Plumbing!
They also gave me a quote for some other work in the future.

One of the most professional plumbers I've ever met, Nick is a master tradesman in the plumbing industry and runs a respectable crew. Coupled with using the best parts in the industry you can't go wrong calling NIR.

I'm so grateful for this business because once they fixed the problem they didn't have to come back. I recommend them highly.

I had a blockage in a pipe that was preventing my air conditioner from draining the condensation. This was causing water to build up under my carpet and also meant that I couldn't use my air conditioner without risking damage to it. I talked with Nick and he set up a time later at night that was convenient for me. His plumbers arrived on time and were able to correctly diagnose the problem and completely fix it within an hour. It turned out that the condensation outlet pipe which was very difficult to find at my condo was clogged up where it exited the house. The price for their excellent service was very reasonable especially given that they came out long after hours. I highly recommend NIR plumbing!
