If your system is gridded it might be pretty hard to pick through the worksheet
to find out what’s going wrong.
To troubleshoot, I’d recommend breaking the grid if there is one so that you
have a much simpler branch system to work through. You might need to flow less
heads temporarily so that yo
Thank you, it must be user error and I did something wrong with my inputs into
HydraCalc. My AutoSprink drawing is clean with all proper fittings for sure,
the safety makes more sense on that calc. Ive used AutoSprink for 4+ years now
but only just started HydraCAD and HydraCalc a few months ago
I use hydra-calc everyday but have compared it's calculations to other
programs with very little differences. With the disparity you're
experiencing I would be looking at pre-set hazen-williams coefficients
being identical, the NFPA fitting multipliers, checking pipe tables for
identical pipe ID, b
Never used HydraCalc but I’ve redrawn systems done from SprinkCad and the
Calc’s were pretty much identical when I was done.
Double check that you didn’t end up with double pipe or Mech tees or
something like that

I was wondering if anyone has compared the calculations between HydraCalc and
AutoSprink calculations.
Ive been messing around with the 2 lately and I am not getting the same safety
margins.
.5 or even 1 psi difference wouldn't surprise me but I am getting 13-20psi
discrepancies. I have triple
