I will use C&L Plumbing every year when I need my sprinkler system to be inspected. Allen called me a minute right after I asked for a yelp quote. His pricing is GREAT! I needed service asap because my due date was in a week. He was able to schedule me the next day. Allen was nice, arrived on time and accommodating.

This is our second year using them for the annual back flow testing required by the city and they did a terrific job again. They are fast, responsive, and affordable. They arrived on time and we were able to schedule over the weekend very quickly for the following Monday. Highly recommend!

We needed an annual backflow test on short notice after our usual guy canceled on us last minute. Great service and extremely responsive with our scheduling needs. Cantonese speaking was a plus. Will be rescheduling with Allen next year!

Reached out to C&L for backflow testing and they were very responsive. Our guy was on time, efficient, and didn't mind our questions. Will be recommending to others in the area.

Allen was on time, provided clear (and speedy) communication and submitted our backflow test electronically. His price was also significantly less than several other places that I called. 5 stars!

Allen was super responsive and got the job done quickly and efficiently. He's super responsive over email and his clear communication made the whole process easy. When we couldn't find out backflow testing forms he even offered to contact the water department directly to get our PIC number. Will definitely be coming back next year

Needed to get an inspection done on our backflow valve and was recommended by our family plumber to Allen at C&L, gave him a call and got a response in a quick and timely manner. I let him know what needed to be done, and he told me when he can come out and take a look. He came by at our scheduled time and took care of the inspection quickly. Efficiency is always appreciated.

I received notice from the city on doing a backflow test. Not knowing what this was, but was referred to C&L by a relative, Allen took care of everything from beginning to end. Allen was efficient and made the process easy as he took care of all the paper work. He is responsive and on-time. Thanks Allen! I will use your service again in the future.

C&L Plumbing helped us with back flow testing devices. Allen was professional and timely. I will be using them for future backflow testing.
