Digital manometer or water is best ?

[Cee pee]

I used my Kane 455 for a tightness test today very accurate

 

[Gray0689]

That's good mate
Just 2 more lol

 

[REDSAW]

water costs nothing to repair?

 

[AWheating]

water is best for a tightness test. 🙂

 

[mutley racers]

Why use water when you have the Kane 455. It's one less piece of kit and mire accurate plus it satires the results

 

[villa_tom]

Water for TT and Antonio digital for everything else. Electronic is essential for fan pressures as you get a more accurate readings.

Anton I mean. iPads on a wobbler

water for soundness testing or TT as its now been renamed,water u gauges never need calibrating,and they never lie,though if you put dark red food dye in them and turn the ECV on to fast they make a pretty pattern on the wall

 

[snowhead]

Water.
Trying to use digital on Commercial T.T would be amusing.

How else would you do a com TT without a digi. You'd be there for hours

 

[EPH]

Testo 510 sits neatly in my servicing case so I use that, can take everything in the property for servicing etc in one go.

 

[rawr]

I used a digital one once and felt dirty all over.

 

[Doodlebug]

Water for me.

 

[dave1]

Water so much better.

Prefer digi here, why people say water for tightness I have no idea. Digital does the job just as well, that said so does a water gauge so each to their own. The reason I like digital are because they are more precise for fan pressures etc, smaller, don't freeze in winter and if they don't need topping up with water every now and then. Also if you do LPG you don't need to store it on the roof rack :biggrin5:

 

[Mike Jackson]

I don't need to store my Regin premier gauge on the roof rack and it does up to 45 mbar. My J gauge will do up to 110 mbar which allows me to test new installations on boats.

Digital is fine for burner pressures etc. but I just don't trust it for tightness testing. How do I know that the digital gauge hasn't malfunctioned? Plus I don't have to get my U gauge recallibrated every year.

 

[Nostrum]

Sounds like it was to early for a spot of light humour! I trust my digital gauge as much as my flue analyser and the consequences of malfunction are much the same. As I said, each to their own. Everyone's a winner and we all get a badge for good behaviour.

 

[stegas]

Good old water for me,with a bit of blackcurrent cordial in works a treat..
Plus i can sleep cause i seen it wid my own eyes.

If you use a digital always keep a u gauge in the van as a back up. There will come a time when you doubt your digital.

Btw you shouldn't add anything to your gauge other than water or manometer fluid as colourings, antifreeze, juice etc changes the specific gravity of the water and will alter your readings.
If you do, a 4mb drop may actually be a 5mb.

 

[quality]

I have both but only rely on water for testing for tightness etc. I have always thought if you don't believe your meter why have it in the van

Using the same logic, I'm just about to kick the misses out the house, after the dishes are done.

Domestic - water
commercial - digital

 

[neily01]

Water all day tried a digital didnt trust it so thought whats the point in that. Been using for a long while regin premier couldnt be with out now!

Domestic - water

So Bod is this about , total system volume

-- Large drop in a small volume

-- small drop on a large volume

for same sized loss ?

or some other reason

 

[Barry98]

Digital because it goes up high enough for strength testing that's all

I would'nt trust an Italian,like Sir Fergie once said if an Italian waiter gives me pasta i check under the sauce

 

[PETE 123]

Water for me. Sick of having to spend on things as it is. So simple is best for me

Apart from the strength testing thing, it is also about volume.

On big stuff you work out the volume of the pipe then multiply it by the grm (gauge readable movement) and a constant factor(s) to determine the test duration.
Say the volume was 1m3 the ttd (test time) would be 21mins (depending what you are testing) with a water gauge or 5 minutes with an electronic.
Over about 1.5m3 volume you are onto a 24hr test with a gauge.
Btw if you ever see the grid mains layers testing their stuff they will be using a gauge.

 

[hammers4spanner]

water for me

 

[stevetheplumber]

regin premier is superb easy to read and spill proof doesnt blow the water out if you a bit to quick with the ecv

 

[BLOD]

I'm a fan of the regin premier as well, the refil liquid is a bit pricey though

 

[grahamgas]

Regin premier 45 here. Also have spare water gauges, one to 30mb, and one to 60mb for lpg work
