Sometimes I think I'm just too lazy to pull the foam bottle off the hand nozzle then I realize I want the flexibility of the multispray nozzle at the same time, I just want it all now!
What I do is have two hoses on each side of the washbay- one dedicated to the foamgun and one for the rinse hose and my other hose attachments.
I've always used a lot of brass quick disconnects and I'm still experimenting with different types of shutoffs.
Each hose has a female brass quick disconnect ("qd" hereafter meaning "quick disconnect" in this post) and all my nozzles/foamguns/whatever get male qds.
Note that the brass qds also function as swivels.
I'm using ones from Gilmour and from Sporty's and a few from unknown sources. All but one (male fitting that only works with certain females) of my brass qd components are compatible.
For shutoffs, I've gradually gotten away from the metal ones. For one thing, I prefer to have as little metal on the end of the hose as possible (plastic seems safer for the car in case I'm careless). Also, I find the plastic ones from Sears/Gilmour are easier to use with one finger and they have built in swivels. Note that these have a large rectangular knob, not the little circular/two-post ones that aren't nearly as comfortable to use. Trouble with the Sears/Gilmour ones is that they leak something awful and eventually break apart. They're still my choice for use with the mitt-balloon technique, where maximum control over the foamgun (i.e., keeping the bottle from hitting the panels) is the primary objective. I too buy them in large quantities and replace them when the leaking gets too irritating.
I'm currently experimenting with
THIS SHUTOFF from Griot's. Because it positions the user's hand farther back from the foamgun, and is grasped in a different way compared to the smaller rotary shutoffs, it does *not* offer the sort of control that the smaller shutoffs do. THis means it's not as good for the mitt-balloon technique on the top horizontal surfaces, but it works *great* for vertical surfaces and for most other foamgun techniques. Very handy for use in conjunction with a BHB. The downsides are that it doesn't swivel (use the brass qds for that) and that it doesn't seem to offer as full a flow as other shutoffs when wide open. This isn't a problem for me with my boosted pressure- I still don't get the maximin volume but I do get pretty much- plenty of suds from the foamgun, more than sufficient. But you'd have to try it with *your* pressure to see if it works OK for you. This is one of those things I'd previously dismissed, didn't think I'd like it at all; man was I wrong about that!
With the Griot's shutoff, I'm using one set of brass qds to attach it to the hose and another set to attach the foamgun to it. This allows both the shutoff and the foamgun to swivel freely (and independently), eliminating my primary concerns about it being convenient to use. But it also increases the overall length, compounding the problems of using it with the mitt-balloon technique.
