Gas pressure tester

[DeliDave_]

Have had my old one stolen from my van with some other kit.The only one available seems to be the Miariad Gok test kit for £300 ish that you also have to have cylinders of propellant to use http://www.miriad-products.com/product.php?xProd=97&xSec=71

Does anyone know where I can buy the hand pump version,I only do a few vans a year so could live with something cheaper if its available?

I simply use "U" tube and water manometers made of clear plastic tube. They were good enough during my aircraft industry apprenticeship days 50 years ago, and gravity has not changed much since

. Add a bike pump for over pressure tests?

I've got two of those one for LPG and a natural gas and one on my Kane analyser but it is required to test vans at 150mb now ,also the needle valve needs a special adaptor.Times change

Anything suitable in the Screwfix catalogue (p 726/7)? I use a Monument dry pressure test kit for checking any plumbing prior to opening the stop tap. Not sure whether it is suitable/adapable for caravan use.

I would have to have the connector to screw on the test point so I think I'm a bit stuck sadly.My kane goes out of range so cant adapt that.Thanks anyway for the suggestion

Dave, the Miriad pressure tester does not need propellant to operate it, the canister is simply a volumiser to give the correct volume of air for the system, its just a reservoir, nothing ele.

It has been since 2004 !

Hi Damian,Thanks for the reply,I have managed to find one for £250.I was replying to JTQ's post of how to do it 50 years ago

Best wishes to you

Not that 150 mB presents any real problem with a water manometer, just a tad ungainly and nowhere near as neat as modern tools. However its very accurate.
