I like this ball valve the best.

All the others I've tried are too stiff. This one is the smoothest.

Everyone with a surface cleaner should replace the gun with this ball valve, to max out your flow.

It will also outlast the gun the surface cleaner comes with.

Put a coupler and a plug on it so you can take it off the surface cleaner and switch to a wand so you can rinse.

yes it is I have a couple of them

I have couplers and ballvalves on both of my reels and all my wands have swivels. Life is waaaaay easier with ball valves and swivels. I would post pick but I still can't figure out how on here!

I had Bob make up a J-rod holder, except I had him weld up the 3/8" plugs - so now I wash homes only with a ballvalve and a j-rod holder - it's house washing nirvana - no more wands!!!!!
