i have an electric kinchrome pressure washer to replace an older one - it turns out both washers when i connect the 12mm hose, the connection point just leaks everywhere

so i got a 18mm hose thinking it would connect better, but it won't even connect to the pressure washer

so i'm stumped

what connection do i need so that the hose connection does leak everywhere or sometimes just disconnects with a nice watery explosion?

the psi is 1300 constant, 1800 max.

i am open to returning the gazillion bits that i bought so i can get a new better set up.

thanks

make sure you hose has a 12 mm fitting on it, and maybe try replacing the fitting on the water blaster with the male fitting from the same manufacture as the fitting on your hose.

Are you sure you're connecting it all the way? Some of the hose fittings click twice, especially those with auto shut off. Connect it all up before turning the water on.

Check you actually have a washer between the adapter and the washer itself. Even if you tighten it up like crazy, if that is missing then it will come out the thread still.

This. Happened to me and luckily a handy cousin came by and viewed me soaked. He knew immediately that the problem was a missing washer and had one in his workshop.

the leak is between the hose click thing and the pressure washer nipple thing though?

that is with the 12mm hose. 19mm hose won't fit at all.

maybe i remove the nipple and take it into bunnings and see if there's a specific hose connector that will give a better connection.

If you have a generic hose end, then try swapping it for a hozelock one - can get from mitre10. They invented the snap on that has become a generic item here so if a clone wont work with their ends, its not a very good clone. I have found that the ones that come on dirt cheap hoses are often not very good at sealing.

A photo of what you've currently got might help.

Most (all?) pressure washers have a tap thread on the machine that you can attach a tap hose fitting to. Check that the rubber o-ring on this isn't pinched or frayed.

But potentially the easiest solution is as above and buying a decent set of matching hose and tap fittings and trying that. I quite like the Holman ones you can get from Bunnings that have a double o-ring.

Oh yeah. It used to be the most nipples and sockets were more or less compatible in NZ. Not so much anymore. You need same brand, same model, same colour fittings. And it isn't just a cheap Chinese import thing.

The icing of the cake for me was when I bought some new name brand stuff (nylex) since I already had that brand, and the new stuff (blue) wasn't even compatible with the old stuff (grey). F#$%#$%^'s.

Thanks, I took the nozzle into bunnings and indeed the cheap and nasty hoses don't connect well but a good hose would fit like a glove
