In your home, within your walls, in your roof or under your flooring are pipes that carry water. They transport water from outside your property through your home to places like the kitchen, bathroom, ensuite, toilet and laundry. At the end of those pipes are taps which when closed stop the water flowing, when all the taps are turned off in your home, and there is nowhere for the water to go, this creates a closed system. In a home with no pressure limits valve installed, the pressure within that closed system is at the mercy of your water supply. The pressure of your water supply is set by your local council, and they will always set that pressure to meet the needs of the community they service.
Most people want as much water pressure as possible and many feel like they do not have enough water pressure to begin with. So why on earth would you want to install a pressure-reducing valve in your home? Here are some reasons that might encourage you to consider a water pressure regulator:
Replacing home appliances — whether it's your water heater, dishwasher, or washing machine— is not cheap. If you have been saving for months to buy the perfect dishwasher for your house, it makes sense to want to do everything you can to protect that investment and avoid replacing expensive appliance parts. If the water pressure in your home's plumbing is too high, that pressure puts stress on your brand-new dishwasher, leading to more frequent appliance repairs. The life of that appliance will diminish exponentially, depending on how high the pressure is.
Nobody wants to shower under a barely trickling shower head BUT the trick is to find the right balance between your water pressure and your wallet. Reducing high water pressure will extend the life of your fixtures, but that doesn't mean you need to suffer through a shower that feels like it's being poured out of a garden watering can. With a pressure limiting valve, you can have a comfortable water pressure that your plumbing fixtures can handle. Besides reducing the harmful effects of high pressure, regulating your pressure means you also can also save water and who wouldn’t want to save a little water?
Most people think they know whether their water pressure is too high, too low or just right. Whilst you may be on track, it isn't a bad idea to have a licensed plumber check it out and give you the peace of mind to know that you are doing everything you can to protect your home and everything in it.
