Unvented Cylinder Service


It is highly recommended that you have an annual cylinder service to ensure safety and to prevent nasty repair bills. If you still have a boiler warranty, then make sure you check the small print as it may be a requirement to have an annual service to validate the warranty. The Red Van Plumbers have undertaken thousands of cylinder services for homeowners, landlords and commercial properties.
If you have a boiler too then we recommend getting the boiler and cylinder serviced at the same time, you would save £30 off the total amount for combining the 2 services.

What to expect

There are many different types of cylinder services so it’s always worth checking what you’re getting. Heppelthwaite the Red Van Plumbers offer a comprehensive service that takes approx 1 hour (depending on manufacturer’s guidelines) – it’s not just a visual check.
  • Isolate and/ or drain the water storage tank and refill once service is complete.
  • Test the expansion relief valve functions correctly
  • Test the temperature and pressure relief valve function correctly
