Is there rule of thumb as to how long set of filters should last? What should I be looking for other than the obvious wear and tear to determine if replacement is necessary? Is it best to replace both filters of a S8M150 at the same time? Current filters are original install, approaching 10 years of year round service.
Good morning Em, There is no really set time for an element. The best way to tell if you need one is. You can look at it .If the bands around it are broken that is one sign. If it looks collapsed or soggy there's another. You can also pressure test it. by running the filter with the element out to see what your operating pressure should be. Then putting the element back in and seeing how much it has raised. If it raises 5psi or more it can be replaced.
