Troy Bilt pressure washer model 020209 has very low spraying pressure. How do I repair the pump?

You are going to need a pump seal kit or they may call it a rebuild kit but this sort of thing happens often and you should not have any trouble getting the parts you need with the kit should come a exploded view diagram but request one just to make sure be careful when putting it back together if gyou damage any of the brass or neoprene parts you will be putting it together for nothing lay out your parts on a clean towel keep all dirt and grime away and clean your pump housing really good before you put the new parts in and i mean clean enough to eat off of if you do all of these things your rebuild will probably last longer the the original good luck and get back with me if you need help with the rebuild
