"I found water on the floor of my basement! Horrors! I got 3 estimates and chose T.QEXCAVATION.Plumbing to do the fix. I liked the work ethic of Terence, the owner who was the guy who did the job. He kept me informed of what was happening and how the project was going, turned the water on when he could and off when he needed to so I had water off and on instead of not which meant the world to me. The job is done, I'm happy with the result and would recommend T.QEXCAVATION.PLUMBING to anyone in need of any kind of plumbing job. He is my plumber from now on."

"They did plumbing services. It was basically the toilet tune-up that they were supposed to do. They fixed it on Friday but on Sunday, it did not work again. Took one more week to get out here and they still have to come back to replace the toilet. At the end of it all, that didn't happen."

Plumbing FAQs, answered by experts

The most common situation in which you should turn off the main water shut-off valve is if there’s a leak in your home, such as in the kitchen or bathroom. Turning off the water supply can prevent further water damage.

You may want to turn off the valve before leaving for an extended period, in case of leaks or pipe bursts while you’re gone. If you’re going to work on plumbing fixtures or appliances, it’s also a good idea to shut off the main valve to ensure no water flow during repairs or installation.

You can adjust your water pressure using the water pressure regulator, which is a valve that's usually located near your water main valve. Opening and closing that valve dictates how much water pressure your house receives. You can also potentially increase your water pressure by purchasing a water pressure booster and hiring a pro to install it for you. 

Yes, you can water plants with water softened with potassium chloride. Potassium is a vital nutrient for plants, so using this type of water is harmless and can even be enriching. It is often a better option than water softened with sodium chloride, as too much sodium can build up in the soil and make it difficult for plants to absorb the water they need. If you notice that your plants are not tolerating the treated water, try letting it sit in a watering can for one to five days to allow the chlorine to diminish.

Besides opting for a professional inspection, there are some other telltale signs that a pipe in your home is ready to go. Keep an eye out for signs of leaks and spot-check exposed areas of piping. Musty smells, spots on your walls, and dripping sounds are signs an unseen pipe has a leak, for example. You can also check the tubing for stains, flaking, and discoloration, all of which are signs of corrosion.

The clearest sign that something is wrong with your galvanized piping is if you can see rust or corrosion on the exterior. These indicate that the same problems are present on the inside of the pipes. You should contact a licensed plumber right away so that they can inspect your pipes. Other signs include poor performance of your gas appliances, high gas bills, and if your pipes are past the lifespan of 20 to 50 years.
