Contacted Clint and we set an appt very quickly. He arrived right on time and checked my problem. He provided a solution that fixed the problem effectively but didn't require tearing any sheetrock. I'll definitely call FlowKo again for plumbing needs.

Details: Only one drain has issues • Leaking (problem area known) • House

Clint was on time and very responsive. He replaced a toilet and faucet. He also creatively solved an issue with a slow draining sink — first identified the issue of too much surface tension due to the drain strainer having holes that were too small and then increased the diameter of three of the holes. Worked like a charm! Cost was reasonable and the work was completed quickly. Would definitely recommend Flowko.

Details: 2 toilets • Municipal water (most common) • Septic tank • House

Clint is an awesome plumber and a great dude in general. He did an awesome job recommending a water softener system. He picked it up and installed it without issue. We’re using him for other work now as well. I can’t recommend him enough!

Details: Reverse osmosis • Water softener (most common) • I would like the pro to buy the water treatment system • House
