    recirulcate is 18 psi.

    could the pump just be wearing out after 3 years?

    Higher pressure either means the pump is moving more water or the flow is restricted in some way that it wasn't before. Is there any chance your valves are set differently than they were three years ago?

    valves are the same way, i adjust em to get the lowest possible pressure also.
