Fairly easy fix. Assuming you have a Wilkins 720A? Black top cap with three screws visible?

Sounds like some cracked or worn out seals.

If so...Turn off the water and remove the screws and black plastic cap. Once removed, you will see a brass/bronze cover with three "sprires" in which the removed screws threaded into. Using your hands, unthread this threaded cap out of the 720A housing. Once removed, you will notice some plastic and rubber pieces inside. Pay close attention to the order in which they are assembled. Inspect all the red seals for any cracks.

Make sure and verify the model number before purchasing any parts. I assume it's a 720A, since it's the most widely used.

If you see any damage on your parts, order a repair kit for it. I'm sure they sell them on this site.
