Re: poppet valves
No, but that is a good question. I think most on here would agree that changing the impeller once every year or every other year is good given how easy it is to do, how cheap it is to do and how much damage can occur if you don't. Poppet valve... not so much but it is important. Mine has a weep hole so that when it starts to leak, you see water coming out where it shouldn't be and you know it needs a change. Does yours have that feature?
