I purchased a Hayward model ec40c92 series filter brand new in June of this year. I installed it and it ran great for two weeks and then I started hearing a noise inside the filter like a loose nut or screw turning around in the filter. I called up the place where I had bought the filter and they came out and found out that the check valve had broken off and had to replace the check valve. Well a week later I get a bill from the place that fixed the filter telling me that the part was covered but not the labor. So I called up Hayward Pool Products and sure enough they DO NOT cover labor charges.
Just thought everybody should know this if they consider on buying a Hayward anything (except I forget which heater it was) that they do not cover labor costs. I never heard of such a warranty as this that they do not cover labor charges after so many days. It will be the last time I buy a Hayward Product, until they change this policy.
