I have an Amanda washing machine that is from 2003, but the hot water valve/tap and hose are from a house built in the late 70’s. I am replacing the hoses and washers/gaskets. I noticed the washer connected to the hot water valve out of the wall has a plastic screen/strainer shaped like a thimble. Can anyone tell me the purpose of the thimble-like shape? Also, does this design have any effect on the water pressure going into the machine?
Thank you.
