John really did an excellent job for us. Very attentive, responded to my calls promptly and cost was very reasonable. We had him come back as we saw water under the dish washer. He came out right away, and found no plumbing issues. Problem has resolved and was not related to the dishwasher at all. We will continue to use GNK plumbing for all of our heating and plumbing needs. We recommend John without reservation.

Details: Built-in under-the-counter (traditional) • Yes, there is access to both an outlet and a drain • Yes, materials and parts will be provided • Home
