  • FAQ

    • Q:What kind of water heater should I buy?
      A:There are two main types of water heaters available for purchase: traditional tank water heaters, or tankless water heaters. When deciding which of them is right for you, the main considerations are going to be upfront cost and ongoing operational cost. Traditional tank models are consistently considerably cheaper upfront than their tankless counterparts. They generally hold 30-50 gallons of water, which are kept heated at all times and sent to the various taps as needed. Tankless models, on the other hand, are generally a much more significant investment, but run more efficiently and tend to have longer lifespans. Also, because they offer heated water on demand, you cannot run out! The main deciding factor for most homes will be what you are willing to invest upfront for longer-term benefits.
    • Q:Why does my bathroom faucet drip when the toilet is flushed?
      A:This is quite a common problem for homeowners. Because your tub, toilet, sink, and shower are all connected to the same water supply, a problem with one can begin to affect one of the others. If flushing a toilet causes a faucet drip, the most likely culprit is excessive water pressure. This can force water to other parts of the system and weaken connections over time. Addressing issues like this early can help homeowners avoid costly, disruptive repairs down the line.
    • Q:Why isn’t my dishwasher draining properly?

      A:If you are having this problem, the good news is that there may be a simple solution to try before buying a whole new appliance. 

      There are several things you can check for on your own to troubleshoot the problem, such as:  

      Check the filter in the dishwasher: Though many modern models come equipped with built-in grinders, debris can still block the filter and cause the backup you’re seeing. Clear out anything that may be blocking this area.  

      Check the hose connecting the dishwasher to the drain line: Make sure the line is not kinked or otherwise visibly blocked or damaged.  

      Check the garbage disposal for proper function: Many dishwashers drain through the garbage disposal, meaning that problems there result in problems for your dishwasher.  

      Check the air gap: Not all models have this feature, but those that do can be identified by the silver device next to the faucet. If water comes out of this device while the dishwasher is running, the clog is between the air gap and the garbage disposal.  

      Check the tube that goes into the garbage disposal: If there are any blockages, they can usually be cleared with a bottle brush.

    • Q:Is there something I can do to prevent pipe leaks and improve the overall lifespan of the pipes in my home?
      A:Preventing leaks is a matter of easing the pressure on your system. If you have cause for concern, you may consider measuring the water pressure in your pipes. A system that consistently exceeds 60 psi could see problems down the line as the pipe shifts under the pressure and causes leaks to form. If your system runs above normal levels – around 30-50 psi – an experienced plumber can help make the needed adjustments on your water regulator.
