So recently the small connector on my water pump pipe (small black plastic bit) broke off completely snapped leaving some of it inside the water pump. We got the piece out and ordered the replacement part, which came in brass. Only problem is it’s slightly bigger than the previous threads leaving it useless. Apparently they replaced the plastic one with brass because of this issue. I don’t want to have to go to the hassle of replacing the water pump though I will if I have too but just wandering has anyone else had this issue and if so was there any way around it ?
