Vito did a fantastic job! I recommend Newflow Plumbing for any job. He also gave me a new hose hook up and a new one for the backyard. Vito not only did a good job, he explained everything to me as well. He was very nice to work with.

I am 75, a widow and handicapped. I am also suffering from severe lung damage. So you can imagine my concern having to call a plumber for an emergency. New Flow Responded immediately. The service was excellent. The young man was courteous, kind and patient. He went above and beyond and fixed my clogged sink perfectly. My doctor demands that folks entering my home wear a mask and this very nice young man wore one with no hesitation. New Flow is my plumber for life. I can not recommend this company more highly.

New Flow Plumbing responded quickly, and arrived promptly as scheduled. The technician, Jeff, listened to my explanation of the events, and even though I commented my expectation that the water heater would need to be replaced, he determined it might be serviceable.
I had another appointment so had to leave while he worked on it. A short while later Jeff called and informed me he was able to fix the water heater, so it would not have to be replaced. What a surprise!
Honestly, I provided New Flow an opportunity to stick me with a big repair bill for a new gas water heater and it's replacement. Jeff did the opposite. He chose to attempt, and succeeded, to make a much less costly repair. This level of integrity is uncommon today. I am grateful to have encountered this.
When I commented to New Flow management about my satisfaction with Jeff, I was told it was normal routine behavior by Jeff, and the expectation for all their employees.
To conclude this rant, I have to applaud New Flow Plumbing for prompt and honest service. I highly recommend them for any plumbing needs.

I can't thank Arman enough. He was gentle and thorough with the troubleshooting. He was patient with me and always reassuring. The issue was resolved and he even had some great ideas for maintenance and other things we could do when we upgrade our kitchen and laundry room.

I had New Flow Plumbing replace my sewer line after it backed up unexpectedly. Arman was great to work with and did an excellent job. I couldn't be there while the work was done but his communication was wonderful as he sent regular status updates and pictures to let me know how the job was going. I would highly recommend him to anyone.

Noticed the cabinet underneath our sink buckling, opened the doors and it was flooded! Started searching for 24 hour plumbers while my aunt called insurance and New Flow plumbing had great reviews with a website that easy to navigate and services clear. Called Saturday after 6pm and had someone at our house Sunday at 10:00am! Gentlemen who answered was patient as we explained our concerns, followed up with text messages and text as they were on their way! Vito found the problem in minutes, explained to us everything that he needed to do, fairly priced, had all the equipment in his truck, and left the area he worked in clean! We had our pipe fixed and water on in under an hour. He was patient with us as he explained how the leak may have started, what to keep an eye on, who’s it may have flooded so quickly, and gave great advice and pictures for the claims adjuster coming on Monday. 10/10 recommend!
