Where can I obtain a repair and parts manual for my HP 80. I also need to know if I can get new contact points for my unit when I get the Safty screw. Also why does the existing screw keep breaking
You can buy them by adding them to your shopping cart. The kit comes with a new safety screw in it. The screw keeps breaking because the diaphragm is ripped and needs to be replaced it's a safety feature so the Hiblow septic pump won't damage itself. You can get new contacts for the pump. They are 32 dollars it replaces the top peice. If the Hiblow has red dust inside it should not be rebuilt the coils are bad.
