Mixing valve?

[JSPeeps]

Is this a really old mixing valve? I removed it because it was leaking and now my bathroom water is only lukewarm.

No. Post a pic of where you removed it from.

 

[JSPeeps]

I'm not sure this will help much.

Looks like a flare x flare gas valve. You smell any gas in the shower ?

It’s not a mixing valve.,

 

[JSPeeps]

It's an electric water heater. That's a copper water line and it's warm to the touch. I took the old valve out and replaced it with what I circled in the picture. Now I have hot water in the kitchen and lukewarm water in my bathroom. That old valve does look like it has an adjustment screw on the top of it.

I believe that’s a gas valve and shouldn’t have been placed in the water supply piping.

It should have no affect on your hot water.

Thats my final answer on that.

Post a pic of the faucet you’re having troubles with.

It's both sink and shower faucets.

I can’t help you then if the kitchen is getting hot water but the bathtub and lavatory are not and you only have one water heater...

Maybe someone else here can.

I've heard some of the new fangled anti-scold valves can go haywire and mess of your hot water in the bathroom. I hope someone with more experience can chime in.

It appears that someone years ago put a cheap gas valve into one of my water pipes for whatever reason. Everything worked fine and my bathroom water was hot until I took the leaking gas valve out and replaced it with a fitting instead. Now it appears I'm not getting enough hot water through the fitting and both faucets in the bathroom only get lukewarm.

Maybe they were using it as a tempering valve

That’s not possible.

Where did you turn the water off to replace this valve ?

Can you post pictures of your water heater piping from a few feet back showing the entire heater and piping ?

Was the valve you removed turned off? It’s turned off laying on the table in the pic.

If it was turned off.....there’s your problem, what you replaced it with will allow flow, and you have a cross connection between hot and cold. This will cause hot water delivery temp problems.

 

[Twowaxhack]

If the valve was off when you removed it, take the fittings you installed out.

And install two of these. One for each side.


To test this theory you could always reinstall the leaking valve then go check the temp in your bathroom and see if it’s back to normal.

 

[JSPeeps]

Yes, I believe it was turned off. I will try what you suggest and keep you updated.

I put two plugs in as Twowaxhack recommended and everything is back to normal. Thank you for assisting this extremely amateur plumber. I very much appreciate it.
