The snake a homeowner had pushed down their own backed-up bathtub turned out to be the problem — it left an obstruction behind, and Sam is the one who worked out why the drain still wasn't moving. That April 2026 call is the shape of the work Saint David's Plumbing and Heating gets: clogs, leaks, faucets, and the occasional heating unit that has quit. Sam is who customers deal with. A June 2026 reviewer put it plainly — he comes when he says he will, he's honest about what he can and can't do, and he's respectful of the house and family. Another June 2026 customer had him replace an outdoor faucet and noted the area was clean when he left; a third called him out that month to service a Navien unit that had stopped producing heat. Drains are where the jobs get involved. A March 2026 kitchen-sink clog was thick enough that the auger couldn't get through it, so the only way forward was replacing that section of drain pipe — and the customer, who still gave five stars, said it took a second visit. The rest is everyday house plumbing: leaking water pipes and new shut-off valves for a March 2026 repeat customer, a leaking kitchen faucet diagnosed and then replaced the same month, a pipe swapped out under a kitchen sink. If you're calling about a stubborn drain, ask up front what the visit costs and what a return trip runs if the clog turns into pipe work.
I recently had St. David’s Plumbing come out to service my Navien unit after it stopped producing heat, and I couldn’t be more satisfied with the experience. From start to finish, the service was professional, efficient, and easy to deal with. The owner, Sam, was especially impressive. He was very knowledgeable and took the time to clearly explain what was going on with the system and how he was going to fix it. He didn’t rush through anything and made sure I understood the process, which I really appreciated. The issue was diagnosed and resolved quickly, and my heat was back up and running without any hassle. Overall, great communication, honest service, and solid workmanship. I would definitely recommend St. David’s Plumbing to anyone needing reliable heating or plumbing work.
Sam is great - I value that he works hard and takes pride in his results, but maybe I appreciate even more that he is an excellent communicator. He comes when he says he will, he’s honest about what he can and can’t do, and he’s respectful of the house and family.
Sam replaced our outdoor faucet and did a great job. He was professional, responsive, and completed the work quickly and efficiently. Everything works perfectly, and he left the area clean when he was done. I would happily recommend him to anyone looking for a reliable plumber.
We had a backed-up upstairs bathtub that we'd tried to snake ourselves with no luck. We called Saint David's and Sam discovered the reason the snake wasn't working. Turns out there was an obstruction from getting the snake down there in the first place. Sam was able to get the tub unclogged in no time. He arrived on-time, left the bathroom spotless after the job was done and charged a very fair price. Excellent work - will be calling again for future plumbing needs.
Saint David's Plumbing and Heating has done excellent and very reasonably priced plumbing work for us on at least two occasions. In addition to fixing leaking water pipes and installing new shut off valves, helping to fix our dishwasher and relocating plumbing, Sam (the plumber) also looked at our gas heating pipes and let us know that he could help install new gas piping and a new gas water heater and replace our toilet as well. His prices compared to others was great and the area was clean and Sam made sure to not track in any dirt etc.. Very reliable, Highly recommend.
