One of the anti-siphon valve, for my lawn sprinklers, leaks. Can I get
replacement washers or O-rings to fix this, or do I have to replace the
entire manifold?

TIA

From where does it leak? What brand is it?

If it is a Mansfield #378/578 and it is leaking from the top try this:

If it is leaking from the handle try this

And while your at it you might as well get a nice new lokking handle,eh?:

All is most likely available at your local hardware store as well. Make
sure you watch how the old one comes apart, and/or take a digital picture of
it so you can put it back together with the new parts correctly.

Hope this helps!
