Unhappy Not getting hot water

I have an American Standard hot water/stream boiler model#1BN-J1, boiler #G-403
Iím having trouble with the hot water. I open the faucet and the water comes out lukewarm for a short period of time and goes cold quickly.

I replaced the mixing valve, flush out the boiler and reset everything back to normal. I still get no hot water at the faucet. The water might get lukewarm and goes cold quickly. Any help or advice will be a greatly appreciated. Thank you Ed.

Ed, did you mean to type STEAM ( not stReam ) ?

How is the water level in the boiler?

The first thing I would do is try to choke the incoming water close to inlet of dom. coil Try this while running hot water somewhere at a decent clip.City water here is better then 150psi.If you got well water another easy thing to try is a product like boil a coil,dom.coil stays in place.Next would be a acid flush which you should hire a pro to do,which I'am sure would rather replace the whole coil or boiler Yes first what Trooper says.

Not getting hot water

Sorry, NJ Trooper, the water level is fine, its where it should be, answerto 2[SUP]nd[/SUP] ?

This morning I Soldered a piece of copper pipe with aball valve so I can shut and open it when needed. I bypass the mixing valve,Once I completed my project I opened the valve and I started getting hot waterat faucets; so the problem lies with the mixing valve. It must be defected,even thought its new, only a week old. Now Iíam going to replace the valveagain and see what happen then. Thank you

One needs to be very careful to flush out the water lines when installing new valves. Sometimes the smallest piece of 'crud' that gets inside a new valve can mess it all up.

Can you remove the 'guts' from the new valve and see if there's anything stuck inside?
