neoprene washers

Our washing machine is in our backyard so I always have to get out there to wash our dirty clothes. Most of the time my husband is the one who wash our clothes. Last week he told me that their was something wrong with our washing. When he checked it was the hose who was broken. Luckily he knows how to fixed it. He went to the parts supply and bought a neoprene washers and it works. I asked him what he did with the neoprene he said he put in the hose. I really have no idea about it, and I am not interested about it. I do not care what he did to fixed it. All I want is for our washing machine to run.
