Pressure valve question

Pressure valve question

PostBy: Dirty Steve On: Mon Jan 30, 2012 11:15 am

My water inlet pressure valve seems to be toast. I was screwing around trying to bleed my second story water baseboard and in doing so lost boiler pressure. After a moment of terror I started checking different components of system and realized my well water was not making up the difference of pressure through the auto fill valve. The valve is inline right after the back flow prevent from the well water supply. So much for whole house filterS and water softner. The units are Caleffi. I finally found them on line and look expensive. Anyone else use these? I taped the brass back flow and pressure valve with hammer- no luck. I guess the back flow preventer could be the culprit also but not sure. My originally plummer loved to use the exotic devices. I guess I'll be heading to local heating store tonight to find cheaper option. I was able to make up the pressure by back filling through my return side of loop from well pressure tank. Put in 15 lbs and held fine overnight.

Hey Steve, I hate to ask the obvious...but are you sure there isn't a valve closed prior to the feed valve? Did you try opening the fast-fill lever to see if that made any difference?

You might be able to clean the valve, they are just a spring loaded needle/seat valve.. it could be just some crud from the pipes clogging the orfice..

I've had luck just cleaning them in the past.

Steve,

If it is this one, turn the valve open on bottom (clockwise)...you probably have it closed.

Yeah, CLOCKWISE to OPEN...reverse logic. :)

I traced every thing out. All other house plumbing is fine. I'm surprised this is an issue- this system is only 3 .25 years old and always had a softener from day one along with two seperate whole house filters. Not going to get the same kind to replace it- that is for damn sure!

I tried every which direction on that valve- nothing. Mine is very similar except it does not have that little gray cap on top of the angled brass projection on the right side of the valve.

I would like to think I could take it appart and clean it but my track record with such projects is dismal at best. But I will try the Caleffi site to get info on a tear down.

Spoke to original plumber. He said take the back flow preventer out and "manipulate" the spring first. Said he has had those stick shut before. So I'll try that first.

Removable filter cartridge
The cartridge containing the operating mechanisms, protected by
a large surface area strainer
, is removable. This makes it very easy
and quick to carry out inspections, internal cleaning and even
replacement of the cartridge itself.

If strainer is dirty, water flow is blocked by the strainer.
The strainer also saved the operating mechanism from being damaged by that debris. ;)

Well I'm back in business. Took off the back flow preventer. It has a screen that only had a small piece of matter on it. The screen was held in by wire clip. Once removed I could not push the spring. Ended up tapping with a piece of wooden dowl and a hammer a couple good raps to get it to move. Worked it by hand a dozen times. Did not stick open or closed. Cleaned it best I could to remove an foreign matter and put it back in. Pressue was still on the money this AM so it must working properly. Solved in 15 minutes and did not cost me anything. Whew!

McGiever, Nice work on finding the technical info on that Caleffi site. Thanks.

Your Welcome :)

As I just put that same exact setup in service here recently, I may find the same trouble down the road too, someday. ;)
