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

Really appreciated Clint’s expertise. I had old leaky copper pipes under my kitchen sink. He replaced the pipes with new (not copper) ones. I also had a bathroom faucet that leaked. He replaced the unit with one that was similar. Thanks, Clint, for a job well done.

Details: No, repair is not urgent • No, the building is not currently flooded • Leaking pipes • Sink • House
