Water Rates Exeter

Water rates in Exeter depend on whether your home has a water meter or not. You can easily find out whether your Exeter water rates are metered or not by looking at your water bill. Homes with metered Exeter water rates will have a meter number listed on their water bills.

Homes that are not metered won't, but they will have the rateable value of the home instead. The rateable value part of your Exeter water rates will have been determined by the local council in the 90s and will probably not have changed much since then.

If you've just moved in or you don't have a bill handy, you can look outside your house or in the front garden for a meter. Sometimes the meter may be located inside your house near to the stop tap.

Exeter Water Hardness

Exeter water hardness is rated as hard water. While rainwater itself is relatively soft, water hardness can change through the water cycle. Due to the way water filters through rocks in Exeter Water's supply area, Exeter water picks up high levels above 201ppm of minerals, such as magnesium and calcium, on the way to your tap.

Exeter water's hard rating means that the hard water in your home will lead to scaling in kettles, sinks, dishwashers and loos. There are ways to mitigate hard water furring or scaling in Exeter.

  1. Baths, sinks and toilets - Use an acidic sanitiser regularly (available in local shops) to clean susceptible surfaces in order to clear limescale deposits.
  2. Kettles - Do not overfill your kettle with water in, general. Make sure that you clean your kettle by half-filling and adding two tablespoons of white vinegar, leaving it for four hours in order to loosen scale build-up. Rinse and repeat to remove scale.
  3. Dishwashers - Take advantage of the built-in water softener. Make sure you regularly top off it off with dishwasher salt in the appropriate compartment.]
