I have warm water coming from garden hoses in front and back yards and it should be cold water. Anyone know what may cause this? Google says it could be a problem with the washing machine hot water valve. Any other ideas? Thanks.

I guess there’s a small chance it could be a valve inside the washing machine? Does you plumbing run through a concrete slab? If the two lines are next to each other and not insulated you could get some transfer, but the hot water would stil need to be running. Try turning the hot water off at the WM and see if it still does it.

I did some online reading up on this the last couple days and found the below response to the same inquiry. For reference, the person asking about their water being warm assumed it was their hot water heater:

It probably _IS_ coming out of the water heater. Easy enough to confirm if you have not been using hot water, and either the hot or cold pipe hot water heater pipes should be found to be unexpectedly warm. Go feel them when you turn on the spigot. I have a feeling that a cross connection is going on at the laundry.

You might have something wrong with a washing machine fill valve (a mixer valve at times) that is allowing water to pass through it, perhaps. You might want to make sure that on yours, the hot comes out really hot and the cold comes out truly cold, when you set the washing machine to those settings. Make sure that the setting is not on warm, either, when you test the spigot temp, again.”

Good luck!
