What Kind of Valve is This in the ground?

[Lucky Pierre]

Valve on right side is on my water supply line. Anyone know what it is? Thanks

The one on the right is a check valve. Prevents any water (contaminated) from backing up into the water supply main.

Thanks! However the other valve in the photo is for irritation (irrigation) shut off. So since direction of flow from city meter is left to right, the check valve doesn’t prevent back flow of irrigation into city system. Thoughts?

For irrigation you should have an above ground vacuum breaker or a reduced pressure back flow device.

Any idea where that pipe goes to? Does it go to the house? We had one post a few years ago where when the irrigation was on (city water), it actually sucked water from the house. When someone was using the shower and the irrigation turned on, the water flow stopped and air could be heard being sucked into the shower head. Might be something similar to prevent water from reversing direction after the tee. As Terry wrote, a proper backflow device is always needed with an irrigation system when tied to a domestic water source.

Thanks WF! The situation you describe is how mine was installed though haven’t experienced the back flow situation you describe. The right side goes to house, left comes from meter, and tee goes to irrigation. According to the plumber I hired, what Terry called a check valve was actually the shut off valve to the house. The plumber described it as an old valve and that on this type of valve the part on top that received the key frequently broke making it useless. Which is apparently why there was no access tube to it when I dug it out—see photos. I Googled ‘Healey’ and didn’t see much (out of business?) and certainly nothing like my valve.

I mistook it for a check valve as well. you got that figured out!

Old Stop and Waste valve. When closed it was supposed to drain and depressurize the house side. Its considered a cross contamination so its good that its been removed.

I put stop and wastes in for irrigation 26 years ago one and only time Id ever seen them . I don't get out much ha ha.
Good point absolutely is a cross connection. Only guess is it wasn't used anyway might want to put a ball valve down there and add a tee with a removeable plug upstream to drain down system if he has a need
