Expansion vessel in a domestic house

[Steve weightman]

Any reason why this cold water expansion vessel would be found in a domestic house it's massive

What's it connected to? Need much more info.

Just connected to a cold inlet the system is unvented with system boiler

Sounds like an accumulator then. Is pressure not too clever where you are?

Alternatively it could be simply what it says on the tin - a darn great pressure vessel in order to give good pressure without drop off until 'much' later...

Do You think it's acting as cold water storage the thing is there's no outlet just cold water inlet connected

No then it won't be. That why I asked.
Sounds like it's simply as I said later on. A huge pressure vessel. The only way you'll know how it impacts performance, is to take it out of the supply or to let all the charge out of it. Hope you have a compressor cos if its a bike pump you're gonna end up like Stretch Armstrong

At that size I'd imagine like said previously, it's an accumulator simply boosting the cold water pressure, it would only have the one connection ,

 

[ShaunCorbs]

accumulator will be connected to the water mains

 

[kris]

I thought he said it was???

I'm back on Tuesday I can isolate It via a lever valve I'll see what happens just seems OTT for a semi detached
