Yesterday i was doing some house washing with my 7x3500 washer and all of a sudden i hear hissing and look back at my truck to see a big ol leak spewing in the air. The female quick connect on the outlet of my zk1 unloader appeared to be bent upwards, where the whip line plugs in. the unloader is rated at 3600psi and i had my pressure set to 3200psi. anyone know what could cause this? i just went ahead and ordered a new unloader and fittings.
no hoses were burst, just a horribly bent fitting. nothing is pulling up on it to cause that.
i already hit down on it with a wrench since i’ve got replacements coming in so it’s not as bent as it was before. but of course that didn’t fix anything
yeah i’ve ordered stainless as a replacement. i’m wondering if the unloader is still good and maybe just the coupler and quick connect went bad? either way those fittings are on so damn tight and with it bent i’m not gettin them off
I agree with @Innocentbystander. And it could be a faulty QC or someone stepped on it, could be a million things. From your unloader you said it goes to a whip line , Where does it go from there? And is your unloader bolted down or flopping around?
That’s likely why it failed. You don’t need to bring out the guns when tightening these fittings. Just past snug would have done it and you wouldn’t have weakened the fitting. Your unloader also doesn’t belong hanging of your manifold either. You’ll crack that head from the weight bouncing on it.
whip line into hose reel. it’s not bolted down but i’m not sure what you mean by flopping around either. i never see it moving or anything. the unloader is directly on the pump outlet. here’s another (blurry) picture that shows more
Male couplings always lead from the pump, but off the unloader your jumper line needs to be jic fittings. Lot of torque and pressure happening there. Plus you seem to have a fitting between the pump and the coupling.
Whip line from pump to unloader block bolted somewhere then whip line to hose reel. Dont need all them quick couplers. Pressuretek.com sells all that stuff.
We dont run a whip line to hose reels like ya’ll do , hose reels are for storage only except water supply. Our chems eat up the plumbing to much in the reels.
