with the wh off no water comes from the hot side.
when you leave one hot side open(on an 8 inch spread lav faucet) then go to another faucet and turn the cold
on water flows out of the hot side slowly.
i think it is a faulty delta shower valve body as i have changed out all the cartridges. any one had this prob its driving me nuts.

are you a plumber? obviously not or you could have solved my problem instead of telling me to call one.
to answer your question ..yes ,texas. and yes this one is
a tough one i've even hired a cross connection specialist
that was a little baffled. psi is 70, psi stays at 70 under a static test(hot side),wh have circ pump w/ expansion tank and check valve, wh are on a tree system which provides equal pressure to each tank,all cartridges insingle control valves have been replaced,all hot and cold lines have been checked for a physical cross connection(all ok)., ok now mr plumber you tell me what im missing.

Jeepers. Throwing insults on your second post is not a great way to make friends here. Especially when your first post is asking for help.

Which company do you work for and what is your license number?

Well I am not trying to get smart here, but I tried to locate a plumbing company by that name and can not come up with anything.

To the members here, remember the rules, no bashing.
Instead of arguing let Nathan or Ron sort it out. If this person is legit, then so be it.

HI Mednick,
Sounds like a cross connection at that particular faucet in question. Turn the other faucet in that bathroom on (hot)and then after you have disconneted both hot and cold lines at the suspect faucet, turn the supply line for the hot side into a bucket and see what ya get.

we determed that it wasnt one lav by checking everyone (8) in the house by alternated faucets .
we also installed swingcheck valves on all the hot sides of the lavs to determine it wasnt a lav faucet(reccomended by that cross connection specialist.......)

medlock,

What type of valves do you have in the house? I'm hope after trying to help you, you will have some good info you can supply to this site, before we get into a help situation, I ask you give us a intro about you in the intro forum, this will help us to know who you are.

If the T&S valves are single handle you might have the culprit right there, they can pass from one side to the other without showing any signs of leaking. You could also have a problem with expansion on a closed system, you have not provided enough info to give any real analysis.

thought of that also....cut the washer box off(it had single hoses to each inlet) also cut off all single control fixtures...laundry,kitchen. the only way possible for hot to be filtering into the cold side is for a defect of some sort in the pressure balancing portion of the cartridge or defect in the valve body itself.i think lol

I don't think T & S makes residential faucets that I'm aware of, I'm thinking there Moen, and a bad cartridge can cause cross over of hot into the cold side even if the moen valve is in the off position.

Well what you might try is replacing the cartridge in the shower valve, I don't get into to much delta here, not a popular brand. see if that works.
