Is there some way that I can tell from looking at my cylinder set up whether it is low, high or mains pressure? (Assuming I have got those options correct).
It's in a 100 year bungalow, and I've taken the cladding off the walls around it, but I can't see anything written on it that would suggest the pressure type?
Any help appreciated. Plumber coming back next week, but if I could clarify it myself that would be good.

The vent pipe out the roof is the clue 3 meter head

there are several things you can look for. low pressure ,look for a pipe up about 2m through the roof. A supply tank in the roof and a saucer sized valve under the tank,It may also have a lable on the cylinder saying what it was high/mains pressure cylinder. A mains pressure cylinder doesn't have these things. Try turning the shower on and see how the hot water comes out,does it hit you hard [mains) or soft [low]. my guess is that you have low pressure unit going on the age of the building.

If you need to get a little more accurate Then for every foot of water height above the top of the tank ( in the copper tube/pipe ) the pressure increases by 0.43 PSI at the top of the tank This is usually the tap levels as well ( not the shower)

It's written on it. Put your hand over the tap and turn it on, can you "hold the water" in? Low pressure. Blows your hand away - mains.

hammer23, this is what the underneath section of piping looks like, so I'm thinking this is the valve you are referring to?
There's no label on the cylinder to say what type of pressure, just the gallons amount info.

It is a low pressure with that valve
