"Plumber was punctual and completed work in professional manner.  In fact, he found a potential plumbing problem with gas dryer connection that could have caused additional problems.  I have used this company before and once again they lived up to their A rating.

"I had plumbing leaks in a couple of places, but the men that did the work went above and beyond by replacing every component involved top to bottom to ensure there would be no leaks for a long time to come. Very satisfied with the quality of work as well as how quickly it was done."

"Aidrian is the best! I had an emergency leak late on a Sunday night and he came right out and fixed everything, game me advice on how to handle repairs and educated me on what to do in the future if that happens. I then had him come out another time to install a garbage disposal. He is so easy to contact, on time, clean, professional and gave me a far better price than anyone else quoted. Itâ s great to see the price he takes in his work. A real perfectionist! He is the only person id trust for future plumbing related issues at my new house."

Plumbing questions, answered by experts

Yes, ammonia does damage pipes if used or disposed of improperly. Although ammonia-based cleaners are commonly used to unclog drain pipes, they either come already diluted or instruct the user to dilute them before use. Otherwise, undiluted ammonia is too caustic and could corrode certain plumbing types, such as PVC.

Sealant doesn’t need to be applied to the bolts, but it can be a good way to stop an active leak in the moment. However, don’t rely on it as a cure-all; instead, make sure to fix the problem at the source by changing or tightening the bolts. 

If you do use sealant, make sure to spread it thickly and evenly across the bolts and the tank's porcelain.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

You should leave the water dripping when temperatures are below 20 degrees for three hours or longer or your power goes out in the winter. Leave the water dripping until temperatures are consistently above 20 degrees and you’ve checked for frozen pipes. With water movement in your pipes, ice is less likely to form, and your pipes are less likely to burst. The drip relieves pressure, preventing burst and leaking pipes.

Pipes should be inspected regularly so you can catch any red flags early on. Common issues that you might run into with your pipes include clogs, damage like cracks and leaks, corrosion, or other signs of wear. When you stay on top of an inspection schedule, you'll avoid costly problems like burst pipes.
