How do I shut the water off in my house?

Every home will have one main water shut off, usually located in the basement of the home. Turning this valve off will shut off all the water to the home when you need to do various repairs. 


Why is my toilet running? 

Toilets can run for a variety of reasons, but the most common is a malfunctioning valve or seized toilet bob. If you cannot diagnose the cause on your own, we're happy to come out and help determine the issue.


My toilet fills up every 10 minutes. What is the problem?

When the toilet fills up more often than it should, it could be due to a malfunctioning valve. If it needs to be replaced, we can do that for you so that the toilet will run like new again. 


Why is my water bill so high?

There could be a couple of reasons that - on their own are small, but together add up to costing you a lot of extra money on your bills. A toilet that runs constantly, taps that drip, and extra-long showers without low flow showerheads, can all cause extra water usage. 


Why do my pipes rattle in the wall?

There are many reasons pipes might be rattling in the walls, and usually, the fix is fairly non-invasive. The problem could be as simple as a loose pipe that needs to be secured to the framing. It could also be that the water pressure in your home is too high, in which case, adding a pressure reducing valve can help. It could also be a water hammer caused by fast closing valves. If you have any questions, give us a call! 


How can I prevent frozen pipes?

If you are worried about frozen pipes in your home, you can prevent them in a few ways. One of the easiest ways is to keep your home's heat turned up to a comfortable level. You can also open cabinet and vanity doors to make sure heat gets into the pipes. 


Why is my hot water not working? 

If you can't get any hot water out of your taps, your hot water tank could be to blame. Your hot water tank pilot light could have burnt out, or there could be an issue with transporting the hot water. 


What causes low water pressure in the whole house? 

The reason for low water pressure could come from a number of causes. The first one could be too much demand: are multiple people using appliances that use water at once? Another cause could be clogged pipes, faulty fixtures that need to be replaced or even a broken pressure regulator.
