some things a bad relay can do are damage other parts that are more expensive to fix, instead of payin 20 bucks for a relay you might have to pay 100 times that amount, now im not sure but if i remember correctly i read something about having a bad relay can send false electrical signals and cause the pump to fail or something along the lines of that, dont quote me on that one though.
