I have an Aqua-Therm 145. The inline pump has a a "screw" for opening and closing the flange on the pump. Last week or two I've been dropping pressure (16 psi down to 10) over the course of a couple days. I've refilled and tried to bleed any air from the system but pressure still drops. So I started looking at everything closely and there is a bit of water in the hole on top of the pump where the screw is, plus a little bit of steam coming off it. So I think it's leaking right there and evaporating off so no obvious signs of leaking or dripping water.
Does this screw have an o ring or gasket that might be bad and can be replaced, or can the whole screw be replaced, assuming it screws all the way out? Thanks

Are you talking about the screw on the pump, if so yes, if you are talking about a shutoff screw on the flanges, no it's junk, replace the flange.

Hey Slim, I called AT and described my system. They said its on the flange, and they no longer have that flange and also recommended relaxing the flange. I can't shut it all down now and attempt this so I'll keep adding water I guess. Is there a silicone or something I could use to try to seal that u on a temporary basis? Thanks for your help.

If it is the round part, wrap some rubber around it and put a hose clamp around it.
-
Nothing that I am aware of that will stick when wet.

At work we sell something called "Through the Roof". It's supposed to stick to wet surfaces, but I'm not sure how it does with pressure. It comes in a tube like caulk, only its not silicon or latex.

I'll have to see if I can take a pic and figure out how to post it here. This "screw" or at least the slotted head or whatever is there is down in a little hole or depression, so wrapping rubber around it won't work. I'll have to replace the flange. When it warms up :)

Kinda confused about this "screw".. Isn't your pump a taco? with taco flanges?
-
Couldn't tell you that. It's whatever AT supplied at the time ('96). Too old and dirty and dark for me to tell at the back if the stove. But I'll try to take a pic tomorrow. Can anyone tell me how to post a photo from an iPhone?

I think what he has is similar to this, only in a flange version. It is a ball valve but you need a screw driver to open and close. (if you are lucky enough to not have them frozen up)

That screw head is almost exactly what I have with the hole in the slot. The only difference is, mine doesn't "protrude" like the one you show. It's slightly sunken in
-
This will probably take care of your issue. Im not sure you will ever get to the screw again.
