Another installation of a Davey 25 inch sand filter by our very experienced technician this morning. This model has specially designed T-Laterals and hub assembly to optimise water flow for efficient filtration, backwashing and water savings, it has a larger tank than average and features a 10 year guarantee on the tank and 3 years on the multiport valve provided by Davey, who have been around over 80 years, so it gives you great peace of mind with the warranty and also for spare parts being available in the future with this model.
