reversed hot and cold

This is a pik of what the plumber says he has to cut a 1x in the back wall to change the reversed hot and cold.

He said after 30 years it is frozen and he cannot turn the brass screw slot etc and I need a new valve.

Hi. probably not reversed hot/cold. Stem on cartridge needs to be turned 180 degrees IMO. Looks like an old moen.

Put in new cartridge and orient it correctly and you should be good.

( Plumber maybe just trying to con you and make a buck)

The brass screw slot is the balance spool. rarely needs to be replaced and thats not your issue...

It's been 30 years and no one noticed the hot and cold are reversed?

If it is a Delta, then, you can flip the cartridge without the help of a plumber. Turn the water off at the valves to the left and right of the cartridge. If the valves do you hold, turn the main valve off to the house. There may be a chrome tube cover on the body of the valve that simply slides forward to remove. There is then a ring located at the front of the valve that goes around the cartridge that simply unscrews. Pull the cartridge, flip so that the notches are aligned the opposite of the way it is now, and screw the retaining ring back on. MultiChoice® Universal Valve : Smart Solutions : Delta Faucet

Its not a pressure balance cartridge. The spool is in the body as stated.

This is probably the cart. If you pull the scald gaurd off you should be able to turn the stem 180 degrees. ( I dont think that cart can be installed upside down. )

This is the spool the plumber is trying to replace.. Again thats not your issue..

Again the H/C may be reversed but I would need proof that this is truly the case. Run hot water and feel the pipe in the wall. Hot is always on the left. If hot comes from the right then yes pipes are wrong. Easier to swap the lines in basement or crawl space if so...

I have only seen h/c reversed once in my 30 plus years as a plumber.

Sorry about the back and forth but I wanted you to have a good look so I don't end up in a mess.
He said I need a new valve.
I live in Leisure World where there are ten floors of old farts like me and the plumbing was done years ago. I guess someone changed this over since the original and a whole tier has to be shut down to get behind a valve. There is no shut off in any unit -that's the way it is.
From what you see here - I hope it is a better view, do you think I can still do this myself. He may have broken some thing. I know he asked me for a bigger screw driver which indicates he is trying to turn a slotted something but I am ot sure if it is the brass in the center or something else. I know this is hard for you because you are not on site but if I can do it I will but need to know if he really does need to replace a valve.

So the guy cant turn the water off?

So if they need to turn off the water you may as well put in a new valve right?

And he has to sweat pipe in the wall and in a hi rise that can be an issue.

Best advice I have for one if a new valve will be installed is to put in a moen... Moen is all I install and use.

Before he breaks the cold side turn off more possibly you should find a different plumber. A small 6" or 8" monkey wrench I am sure will be able to turn that stem. Its washer less design and only a simple 1/4 turn stop. I find it hard to believe its stuck..

Sorry to confuse you.
He can turn the water off.
What should I tell him as he is the plumber for the building.
I don't like cutting the wall on the back side which is in a living area.

No have him read the thread.

Tell him im a plumber and if he can turn the water off he can change the cartridge..( not needed unless its dripping)

Infact first have him prove to you that the hot and cold is reversed.. meaning hot water comes from the right side pipe in the wall.

If its not reversed then simply turn the stem 180 degrees. You dont even need to turn off water to do that.

This vid shows a reversed h/c line and how to turn the stem.

If its reversed lines or not turning the stem will fix your issue period!!!!..

Show the plumber this vid...

I will show him and I cannot thank you enough. It will be interesting to share the video. He is s nice guy and will cooperate.
I wonder if age of the faucet has anything to do with it but then again you saw all the pictures. I did not see the red and blue piece but it might be a different color due to age.
He is coming Thursday and I'll let you know what he says.
Thanx again.

Delta

I just wanted to reiterate that in post #4 I stated this is a Delta not a Gerber as the video shows. Maybe there is or is not a difference.
I don't know if you saw that.

Should make no difference. All those faucets work similar..

But if that dont work please let us know here on the forums.

Basically I am intersested in

1. is the h/c actually reversed?
2. Does spinning the cart stem fix the issue...

Thanks,,,,

If the valves are open and the faucet replaced and with the handle on, shouldn't water come out when turned on? Either way the piece you move inside to regulate 180 is up or down?

Not sutre what you mean faucet replaced. you mean cartridge?

Yes water should come out.

With both shut offs open and the handle replaced and with the 180 movable piece in either direction no water comes out.
Besides the big slotted piece there is no other shut off except the buildings main.

The pipes are ok hot on left and cold on right.
Moving the movable 180 piece shown, does not even turn the water on. See the post to lawrosa.
I am not sure the Moen feature works here. I know the brass slotted piece is frozen as there is another on my tub floor in the package.

Do you get water at all?

I see its a shower only.

If no water the shower head is clogged..

What is the original issue??

I think we are going in circles...

I know the brass slotted piece is frozen
You can get that open with a wrench. there are flats on it,

solved

A different tech came up and the pipes were crossed - BUT - he had another Delta cartridge that was also backward - defective.
In other words 2 wrongs made a right.
I am sorry about the confusion but I was a wreck over this not knowing how much it MAY cost.
Thank goodness for the second plumber.
Thank you very, very much for your cooperation and support.
He snaked a wall and the sink is fine and replaced a toilet valve which is fine also. Our contract means we pay for the part only. - $ 30.

So what did he do actually? Just replaced the cartridge?

How did he determine the pipes were crossed?

>>So what did he do actually? Just replaced the cartridge?

He opened the valves on each side which I did not know how to do and turned the water on. The pipe on the right was hot to the touch.

He said Delta made a batch of defective cartridges which were backwards like the pipes. He had some and installed the backwards cartridge into the backwards crossed pipes.

By the way, he said under normal circumstances the Moen concept of turning 180 would not apply here; it could not be done as the cartridge would have to be replaced.

The first guy they sent from Leisure World shop was not experienced or licensed. This person was both.

I hope I have clarified all for you and thank you once again.
