I have recently installed a new washing machine. In the new machine, as well as for the old one, there is a leak as indicated in the following picture:


What could cause this? I have screwed the clamp tightly by hand - should I be using a tool to do this?

Note: this is on the cold side, and the hoses are new, but the faucets old.

    Looks like the rubber / fibre washer is missing – SiHa May 13 '20 at 9:01

    Either a missing seal washer as @SiHa says, or a damaged sealing surface on the faucet (a picture of the business end of the faucet with the hose removed might be helpful.) – Ecnerwal May 13 '20 at 11:41
  • hotglue the seat if you can't get a washer. – dandavis May 13 '20 at 16:12

Make sure there is a washer in there. Compare it to the hot water side for the washer.

These fittings always say "hand tighten ". I have seen very few that tighten sufficiently by hand, especially when dealing with head pressure. Take your pliers or Channelocks and give the nut an eighth of a turn further than your "hand tight".

There should be a rubber "rubber" washer in the plastic union that screws onto the tap.

(the washer is usually some sort of flexible plastic, not actual rubber)

It's called a hose union washer and should be available at most places that sell hardware or plumbing supplies.

I have in the past used slices of actual rubber hose to replace lost washers.

If there is a piece of fibre in the joint that could cause a slow leak. so when you undo the union to check for the washer, if you do find a washer make sure that it and the surface below it are clean and undamaged, and that the mating face of the tap is also clean.

  • A little Teflon tape on the threads wont hurt either – Scott May 14 '20 at 0:52
