Very disappointed to see that the purge time remains the same for a 15mm purge point as it does a 50mm Something very wrong here hey
This is fine for domestic and medium-sized commercial installations, but where it falls short is on calculations involving larger internal volumes. I find that once you get up to about 1.8 cubic meters or above, it simply errors and does not give purge and test times at all. Furthermore the steel pipe sizes (a) are given in mm when steel is always measured imperially - in inches and fractions (b) only goes up to 150mm - six inches - when eight inch, twelve and above are common. Disappointing app that really could be indispensable with these small changes.
Yes the calculator gives TTD but the calculations above do no indicate IVmeter so does not give IV to total I expected the calculator to allow for maximum permissible leak rates, but sadly it just works out the purge volume and TTD although given i had to manually work out to see if it was correct NO TTP nor let by period Unfortunately the app is sadly lacking however it does work out the pipe volume correctly !
Does not offer standard UK sizes for pipework or even press systems. No 35mm, 54mm, 66.7mm etc etc Update, I was referring to press systems, Mapress, Xpress, M-Press etc etc What about Stainless or Carbon Press? Copper and barrel are old hat these days
Bought this in the hope that all the other reviews were wrong and somehow it would be ok for me, tested it on a tightness test that I had already calculated, true system volume was 0.95xxxm3, the app came out with 0.85xxxm3 and said the test time would be..... 2 minutes!!!!
Load of rubbish!!!! Will be asking for my money back!!! Not paying every time I want a calculation! Much rather pay £50.00 for one that works every time and not charge for the results each time! Do not buy!! It’s a scam! They don’t tell you that you need to pay for each result!!
Was a good app when I bought it until I realised the calculations were somehow wrong. I worked one out today using the book (did it three times) & came out as 191 second purge time where as this app said 94 seconds ! Be using the trusted book next time !
Dear buyers be careful from this apps because not good at all. I Used this apps for couple weeks suddenly I realised the calculation is in correct. From now I am using my book.
What a load of rubbish cannot believe Ho bad !!!!
