The experts always tell you to dry fit all fittings before committing to glue.
I admit I don't always do that and I have got caught once or twice.
Most of the A B S fittings are three quarters deep but they also make some arc
which adds a little to the length.
I don't know if there is an absolute standard. There are at least two sweeps of
elbows, a long and a short curve. The only way I know of calculating the
additional length added by a fitting like an elbow for example is to set one
opening on a flat surface and measuring from that flat surface to the top
inside of the opposite opening. You will then have to account for the three
quarters of an inch which disappears into the end of the fitting.
PVC as is used in pressured water lines are all sharp bends, or at least any I
have seen or used. I am pretty sure all that I have used are half inch deep but
just now I don't have any spare 3/4 inch fittings to double check that with.
My advice though is to always dry fit before applying the solvent. Sighted
people draw pencil marks across the joints to line them up after when glue is
applied so you don't have to glue them in situ. I have always winged it but you
could lay masking tape across the joints then cut it with a razor knife before
disassembling the fit and applying the solvent and then use the tape to line up
the fittings correctly.
Hope this gives you some helpful ideas.

Subject: [BlindHandyMan] PVC Question For The Experts
Hi all,
I've done quite a bit of work with PVC pipe but, at times, when I glue the
pipes together the parts turn out to be a little too long even though my
measurements are very accurate. Is there anykind of a rule of thumb for
taking a little off each measurement to make things go together better? Any
help greatly appreciated.
Take care,
Ed Przybylek
