There are a few things that people don’t realize when they shop around for a new water heater install. Many people just call to get the lowest price but with the lowest price the Orlando plumber may cut corners and you will not know unless you know what you are looking at. One of the things that new Orlando water heaters need are either an expansion valve like the Watts 530 or an expansion tank. These are to be installed on the cold side and are now code. These little devices do cost money to install so you should ask if the lowest Orlando plumbers quote is going to include this.   A lot of cities in Central Florida are now installing double check valves at the meter and when they install this device it keeps anything toxins from going from your water supply into the cities water supply. In return when your Orlando water heater heats up at night and no one is using the water and the water expands because of the heat there is nowhere for the pressure to go, so it leaks water out of your T&P valve wasting water or worse if it is in your home flooding your house. Expansion valves or tanks are a must when installing a water heater in Orlando.
