Re: Pressure relief valve mounting
The loops in the floor, im filling them pushing the air out the other end, so it's wide open.

Re: Short cycling boiler. I'm stumped.
It's recommended by the boiler and expansion tank manufacturers to check the expansion tank air pressure annually. I do this on all of my boiler maintenance jobs and I have found that the tanks normally lose a few PSI every year. I'm surprised if I find one that still has the same pressure in it as it did the year before.

Re: Expected operation of Gorton #2 during off cycle
So long as those return lines drop down before they tie together, that all sounds quite reasonable — and it's not unusual at all to not hear Gorton #2s in that setting. They're pretty quiet.
And there's no real harm to having the basement warm — and if you want it warm, you are not wasting the oil, are you? The main advantage to insulating mains isn't really the heat loss, but getting heat to the actual radiators a little faster.
Re: Expected operation of Gorton #2 during off cycle
If the system heats fast, I wouldn't worry about it. Perhaps when the boiler shuts down the steam collapses in the radiators first, but I am sure the Gorton's are letting air in. Sounds like a non issue.
Re: Short cycling boiler. I'm stumped.
@PC7060 said water coming out of valve is solid indicator of failed tank. You should be able to pick up a new one at local big box.
Ouch. Water from the air side of the tank is a definite sign that the tank must be replaced.
There are two types of expansion tanks You want the one for a closed system that comes pre charged to 12 PSI. They are usually Gray or Green. The other type is for an open system like your hot water heater and comes pre charged with over 45 PSI Pressure. They are often White
When you get your replacement tank, you want to fill the air side of the tank with 15 PSI because the Watts 1156 will make the water side 15 PSI. Check that air pressure before you install the replacement tank. That way you will be sure that you have it set correctly.
For now you can still operate the boiler but it will discharge water thru the relief valve if the pressure gets above 30 PSI. Don't worry, it is only water. You can close off the manual feed valve for tonight so you don't keep adding water after every overpressure event. The operating LWCO will protect the boiler in the event your water level gets too low.
Re: Short cycling boiler. I'm stumped.
Yes, sadly, you'll need to replace the tank. The problem with this is that you'll have to go through the entire draining, refilling, and purging procedure all over again. Sorry………….the pitfalls when the original installer did not include the necessary valves to isolate various components in the system.
The tank is precharged to 12 psi. Raise it to 15 psi before you install it.
