"I can't thank Steve enough for the work he did for us.  We had a few small parts of our Central AC system that had fried on us.  When we called Steve the temperature was 95 degrees and he understood the need to repair the system as soon as possible.  He came out within 24 hours, diagnosed the problem and returned with the proper part to fix it.  He was the 4th person we had look at our system and his quote was by far the cheapest.  My only regret is that I am just now writing this review instead of doing it after the work was done.  We found Steve to be professional, prompt and very nice to deal with.  We will certainly use him again if needed.

"I had a leaking faucet Andrew was quick to respond. We went over a couple options but i decided to go with a new faucet swap. Andrews pricing was very affordable, he showed up when he said he would he was clean and his work is high quality. I will definitely be using this business again for my plumbing needs."

Plumbing FAQs, answered by experts

Some of the problems with in-wall toilets include the complex installation, which might need extra framing. It is also more difficult to access the toilet tank for maintenance or troubleshooting because it’s behind the flush button panel and in the wall. Over time, you’ll spend more on maintenance because you’ll need a plumber to work on hidden plumbing.

You can often identify a freeze-proof faucet by its structure. Unlike a traditional spigot, a freeze-proof one will include a long supply pipe that extends into your home and connects several inches back to your water supply. Many freeze-proof models also have an extra valve on top of the exterior of the spigot, which is the anti-siphon feature that protects against water backflow.

For a fully-foamed hot tub, freezing typically occurs when the temperature drops below 28 degrees Fahrenheit and remains at or below this level continuously for a minimum of 36 hours. If your hot tub and pumps are still operational, however, the water circulates, and this continuous movement helps prevent freezing, even in very cold conditions. This circulation, along with the insulation provided by the foam, helps maintain the water temperature and prevent it from freezing during extended cold periods. Still, if you’re not planning to run it regularly, be sure to winterize the hot tub properly to prevent damage from freezing.

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.
