Had a great experience with this sewer and drain company installing our new water heater. The team was professional, arrived on time, and explained everything clearly before starting the job. The installation was done quickly and neatly, and they made sure everything was working perfectly before leaving. Really…
HONEST, reasonable price, and reliable business. Had a clogged kitchen sink. Called one plumbing company and was diagnosed there is a cracked in the pipe drain. Called Fanti Sewer for a second estimate and Rob was able to come out late in the evening. It was just debris build ups in the pipe drain and there wasn’t any crack in the pipe! Rob thoroughly cleans out the debris build up through the camera and explaining the routines of the work. Definitely will call Fanti Sewer for future needs. Thank you Rob!
Response from the owner · 2 weeks ago
Hi Lynda, thanks for sharing your experience. We’re glad a second opinion and our camera inspection found debris rather than a cracked pipe, and that Rob could walk you through the work. We appreciate your trust and kind words about our honesty and pricing. We look forward to helping with any future plumbing needs.

We had to fire our original contractor for terrible work after starting a kitchen remodel, but Rob and the fanti crew totally saved the day on the plumbing side. He called ahead to give me an arrival time, talked me through every step, and put in our faucet, disposal, and soap dispenser before coming back the next day to wrap up the dishwasher install. Everything he touched looked clean and done right, worlds apart from what the first guys did. If you need an honest and great plumber, here is the right team! Glad they are based in Cerritos!

Emily, we appreciate you sharing this. We're glad we could step in during your remodel, walk you through the work, and complete the faucet, disposal, soap dispenser and dishwasher cleanly. Your recommendation and trust in our Cerritos team mean a great deal.
Annika Altares2 reviewsiTotal number of Google reviews Annika has written across all businesses on Google Maps, not just this one.
We recently had a pretty serious water leak outside. I live in Cerritos, and the local plumbers here were too busy to fit us into their schedule for over a week. It was hard to even get a return phone call!
So I reached out to Rob and he responded to my estimate I put through the website within about 10 minutes. He was able to come out to see us a couple days later and had his guys on the job really quickly.
The guys were so professional, and the repair job looks really well done. I'm so happy that they came all the way out here, and I would not hesitate to call them in the future for any other plumbing issues I might have.

Annika, we are glad Rob responded quickly and our team could reach you in Cerritos to take care of the outdoor leak. It means a lot that you found the crew professional and the repair well done. We appreciate you trusting us with the job, and we would be happy to help with any future plumbing needs.

Great work. The only company that came out that day. Professional, honest, a little pricey for me, but plumbers are important especially ones that you trust. This 1952 home had an electric stove forever. To save money and improve efficiency we got a nice gas stove, but to use it we needed it converted to an existing gas line. They installed a safety valve, verified for leaks and helped me install the stove. A full service company. Rob did a great job
Response from the owner · a month ago
Thank you, Bob. We appreciate you noting our same-day response and honest service. We're glad the safety valve installation, leak checks, and stove hookup made the conversion smooth. Your trust means a lot to our team.
Ariel4 reviewsiTotal number of Google reviews Ariel has written across all businesses on Google Maps, not just this one.
Our garbage disposal and kitchen sinks were completely backed up for days, and none of the home fixes I tried worked. I saw good reviews for Fanti and called them this afternoon. The office booked me right away, so happy for a SUNDAY, and Rob called ahead before arriving in about an hour. They asked questions, checked the sink, and snaked the line without trying to upsell me. Rob even used a small camera to show us the clog. We will definitely use them again if something breaks.
Response from the owner · a month ago
Thank you, Ariel. We are so glad we could resolve the backup on short notice on a Sunday, that our technician called ahead and used a camera so you could see the clog, and that you felt there was no upsell. We appreciate your kind words and will be ready to help if anything else comes up.

I had a broken pipe it was gushing down below where the pipe was. The FANTI team showed up within 10 minutes of my call. The only tenant here who needed water immediately opted for Rob to show up the next day. Him and 2 others came found the problem, turned off the well and gave me an estimate. They fixed it, I had plastic but we did brass, turned back on the well and I'm happy!

Thank you, Johanna. We are happy our team could respond quickly, locate the break, complete the brass repair, and get your water back on. We appreciate you sharing your experience.
Sofia “Sofia Bella” Erskine2 reviewsiTotal number of Google reviews Sofia has written across all businesses on Google Maps, not just this one.
My main sewer line was clogged with a huge ball of thick roots at about 47 ft from the house. Rob, the owner of the business, himself came twice. With his experience and superb skill he demolish 100% of the roots using the snake with different cutting attachments. This saved a digging job that would have costed thousands. The charge for the excellent work was more than reasonable. Highly recommended!
Response from the owner · a month ago
Thank you so much, Sofia! We truly appreciate you taking the time to share your experience. We’re so glad Rob was able to clear the root blockage and get your sewer line flowing again without the need for a costly excavation. Thank you for trusting Fanti Sewer & Drain and for the wonderful recommendation!

I called in about a possible leak and they were ready to make a same day appointment. They took the time to walk me through steps over the phone to confirm whether or not there was a leak and they taught me a lot about plumbing sounds and what they typically indicate. I appreciated how patient and helpful they with me.

not kevin5 reviewsiTotal number of Google reviews not has written across all businesses on Google Maps, not just this one.
I called Fanti for a water heater replacement because there was a leak in the copper pipe. Rob came out and changed the old valves to newer ones + replaced the water heater and pan. I called them again for a sink that needed a p trap and Rob once again came to provide his exceptional services. He gave me his opinion, and with my approval, he cut the back of the drawer so that the sink drain wouldn't be bothered. Every step of the way, he asked that I come check: the cut of the drawer, the drain, and finally, to confirm that everything was finished.

I had a bathtub drain that wasn't draining for weeks and then suddenly water was coming up my drain when my upstairs neighbor would use their bathtub. That's when I decided to search for a plumber in Cerritos and Fanti Sewers. I called them on a Saturday night on an emergency call and a plumber came the next day on Sunday morning. Rob, the plumber is GREAT. A very nice, hard working and knowledgeable guy. He fixed my drain issue in no time and my drain is finally draining. The price for an emergency visit was very well priced and I will definitely call them again.
