possible leak

Hi- I need some advice on a possible leak on my boiler
(Weil McClane 68). The water feeding the boiler doesn't go through a PRV like I've seen in other set-ups. It comes from my water softener, which is fed from my well pressure tank.
Goes through the ball valve with the red handle seen in the pics, and then into the fitting that my expansion tank hangs from. My concern is the corrosion you can see on the back of the fitting - it looks like a hex head part screws in and uses a gasket to seal? Everything on the boiler works fine- pressures, temps, burner, etc. I'm just worried about a possible problem developing, and how I should deal with it.
As always, thanks for your advice and have a Merry Christmas!

Steve

Corrosion

The device into which the water feeds is called a Fill-Trol. It is a pressure reducing valve which works off of the pressure in the tank. I much prefer a separate reducing valve but the Fill-Trols do work. Since winter is upon us, I suggest leaving things alone until spring.

I believe yer restricted to using their special tanks too... do supply houses carry them Grady ? I bet they're lots more bucks than a standard tank...

And to adjust system pressure with one of those, you adjust the air pressure in the tank ?

Fill-Trol

Trooper, yes they do need a special tank which comes with the valve assembly & they are about 50-75% more than a regular tank. Most supply houses do carry them. Not sure about home centers.
You are also right about adjusting the fill pressure by adjusting the tank pressure.

leak?

Grady- what am I facing in the spring? Is there a gasket or o ring that can be replaced? As far as I can tell, this system is about 15 years old. Should I just install a regular PRV and do away with the fill-trol? As always, I'm grateful for the advice.

Gasket

About the only way to replace the gasket is to make one. You can't buy just a replacement gasket. Getting that plug out to replace the gasket is often next to impossible anyway.
Judging from the proximity of the shut off valve to the Fill-Trol, it would be cheaper & much easier to simply cut the copper pipe, install a new Fill-Trol & a union. If you don't mind the extra work & slightly greater cost, I prefer separate components.

leak

Thanks for the info. Once we're into some warmer weather, I'll tackle the gasket, and if I can't get it apart, I'll go with separate components. Thanks again!

Steve
