My washer is kaput.
It is the thermal relief valve that has started to leak.
Any ideas how to replace this?
I have researched a 3/8 valve on email but this would require tap and die kit to fit this.
It is a shame because the main unit is OK.
There must be thousands of these that just need this replacing. Better that than buying another unit. We need to move away from a throw away society.

I looked up the RAC washer and it seems it's made by Karcher, but without knowing the model number it's difficult to help.
But checking on mymowerparts.com (not an endorsement, just a source of information) they list lots of service manuals for Karcher products with part numbers.
Chosen at random, so it's probably not yours;
https://www.mymowerparts.com/pdf/Kar...HH-K5800GH.pdf
It shows the part number for the complete thermal valve as 4.580-360.0
Running that number through Ebay I find:

So if you go through the same steps but using the Karcher model you have it may find the part you need.
Best I can do I'm afraid.

It's a bit silly for audreywetmore to extol the virtues of the pressure washer when the OP is asking how to fix his because it's broken. 🤣
