"I called to have someone look at my basement drain backing up. The first person quickly diagnosed the issue but didn’t have the camera needed to look at the line. This was a bit annoying since I was very clear in describing the problem before he came out. However, another guy came out first thing in the morning and did a great job diagnosing the issue and took the time to show me and explain his assessment, along with options. They charge $65 to come out for diagnosis. My total for over an hour of camera work on two lines from inside the house and diagnosing the issue was $326. They were both professional, punctual, and didn’t waste time. The second person was honest in telling me not to try something that I think other plumbers would have charged for. John M was a pro and I appreciated his service. I’d use them again."

"Very impressed with the professional appearance and demeanor of the installers. They initiated a series of pre install checks around the home that solved some issues and found a few problems that needed to be solved before they started. On top of going the extra mile, the install was successful and I'm a very satisfied customer. The manager was responsive and accommodating. Highly recommend Dunn One Hour Plumbing, Heating and Air Conditioning."

"This is a good company to deal with. James, the owner, was out within one hour to diagnose our problem. The next morning the technicians, Brian and Josh were out to take care of our drain issues. Brian made a point of showing me the camera footage of the main drain. The did a great job on the main and two other drains. They also cleaned up very well when they were done. Brian also noticed an issue with our bathtub stopper and fixed it without an extra charge. The pricing was transparent. They have a nice email notice system and called when they were on the way. The three men I worked with were all very professional and easy to deal with. I would not hesitate to use them again. Phil Lykens"

"My positive experience initiated with Jason answering phone and calmed me down because I was frantic. No water from the showers, sinks and the toilet did not flush and refill. Two other companies had attempted to solve my problems but were incapable of doing so. Tech Everett arrived early on the same day I called. Within thirty minutes, he resolved the issue!! He was very respectful, professional, and knowledgeable. I highly recommend Drain Surgeons and thanks again Jason and Everett."

FAQs for plumbing projects in Saint Louis, MO

You can absolutely install an outdoor mixture tap outside your home. An outdoor mixer tap blends hot and cold water before it leaves the spout, giving you a steady temperature for rinsing produce, washing hands, or spraying down patio furniture. As long as a plumber runs both hot and cold supply lines and insulates them against freezing, a mixer outside performs just like the one in your kitchen.

Outdoor faucet handles come in twist, lever, or knob varieties, all designed to stand up to the elements while giving you precise flow control. They’re built from tough materials yet offer the same comfort and ease of use as indoor faucets. Ask your plumber for a selection and for recommendations on the best option for your needs.

Start by pinpointing the leak—often it’s a worn washer, a loose packing nut, or a damaged gasket. If it’s salvageable, replace the faulty part; otherwise, you may need a new faucet. Always turn off the water before starting repairs, and test thoroughly when you’re done to confirm you’ve stopped the leak.

You can protect your outdoor faucets during the winter months by shutting off the water supply to the outdoor faucet before freezing weather arrives and by always disconnecting any attached hoses. You can further safeguard your outdoor faucets against ice by insulating the pipe and installing a basic faucet cover.

An outdoor faucet can last 20 years, though budget models may wear out in 10, and high-end ones can push 30 or more. Proper installation, routine upkeep, and careful use help you get the most life from any spigot. Ask your plumber for maintenance and care recommendations to get the most from your outdoor faucet.

Replacing an outdoor spigot yourself might work if you’re handy, but a professional plumber guarantees code compliance, reduces the risk of water damage, and offers peace of mind. If you’re not sure about soldering or local regulations, it’s best to hire a licensed plumber for a lasting fix that you can feel confident in.
