Water system question

[dld0517]

I think I goofed when I re-plumbed my AS. I pretty much had to tear out everything, which is where the question comes in. Does the pressure regulator include a one-way check valve? If so, where can I get a replacement? Or is there another way to accomplish the same thing with off the shelf plumbing parts? It works fine as long as I'm connected city water, but as soon as I pull the hose, the system drains back through the city water connection. Any help would be appreciated. Dave

You can find a check valve at any Home Depot or Lowes in the plumbing department, they are not part of the pressure regulator.

Those pesky valves, when clogged, can make things tough.

You can buy a gate valve at HD or Lowes or any plumbing supply.
You can even buy them with hose connections. They will thread directly onto your hose fitting and simply close the valve. Voila! no back "spray"

FWIW, nowadays, some new regulators have a check valve built in; I noticed this fact when looking at new units to replace my home reg.
