What reviewers report — the concerns

Red flag
1 of 5 reviewed calls ended with wrong diagnosis and a $525 combined charge for work the Water Company resolved as a PRV valve replacement — customer labeled plumber 'incompetent.'
“No water pressure in the shower and he tells me to buy a new shower head because nothing else is wrong all looks good. Paid him 175.00. 5 days later no pressure so I called the Water Company, they said you need a "PRV" valve because they only last 1-3 years and my plumber should have know this fact.”
Missed PRV valve diagnosis: charged $175, told customer to buy a new shower head, then returned at $350 — Water Company correctly diagnosed PRV on first inspection.

The evidence — in reviewers' own words
Positive
“I highly recommend Johnson Plumbing. I had a small leak in my waterline up by the road for a "1 1/4" PVC pipe. I had a similar leak replaced by a big plumbing chain and they charged me $2480.... Johnson Plumbing did the job quicker and just as good for $375. They are a family owned business and treat you like a friend, not just a customer. I recommend you include them in your quotes for any plumbing work.”

Thomas has been the plumber who comes out and he’s been reliable knowledgeable and straightforward each visit. He explains what’s going on without overcomplicating things and the work is always done right. …”
