all pools will be basically the same. Everyday new unit(s) will put low
vacuum to full vacuum. Cutting the hard plastic hose is a big deal, haven't
done it yet in 30 years, and its a yearly function.

Thanks, that sounds like god info to work from, and I should be able to
find the problem wihout having to replace things. Just so I am clear, I
guess the the O-ring seal on the strainer counts as part of the suction
side, so I will start to start troubleshooting there and work backwards.

Working backwards, parts include:
Pump
Rubber O-ring and groove in plastic pump housing
-correction; the spray I use is teflon:a petroleum distillate suspension
Plastic bowl screen (the plastic top rim that supports it in the bowl of
mine is cracked - its an old unit and may be n/a, so I am told
-so I may try improvising plastic sections to try to make a complete seal
around top
~8" Plastic straight pipe (threaded 2 ends)
Ball Valve (threaded 2 ends)
90 degree plastic elbow (threaded valve end, smooth hose end)
~16" rubber hose (new fibre-reinforced white)
90 degree plastic elbow ( smooth 2 ends)
Eternal hard plastic pipe section (leading down into ground and over to
skimmer)

The Eternal hard plastic pipe section (leading down into ground and over
to skimmer) has never been cut in 30 years. So the imprint of the 90
degree plastic elbow grooves ( smooth 2 ends) which have been imprinted
into that hose, and the fact that its hard platic, mean the seal may be
not perfect. But therer are 2 pipes there (one in, one out) cut both the
same length. They are about 18" up from the ground, probably no elbows in
the ground, cause you can see the curl of the hoses and strain. I could
cut them down and get new elbows with new pronounced groove ridges, put
the kettle on, and clamp like hell while pliable.

Each winter I take off the clamps, but the ~16" rubber hose (new
fibre-reinforced white) is the only piece separated and taken from its
place- the pump keeps the straight pipe, ball valve and elbow attached,
and the pipe from the ground keeps its elbow (minus the SS clamps). I
could try troubleshooting the possible leak points, but every year I work
like hell to get em not to leak at the outset - but its a vacuum so who
knows!?

ANy thoughts?

The head I a talking about is at
the top of the filter (tank), the section with a round flat base that
bolts to the main tank section with the 6 or so bolts.

Repeat: Bubbles indicate a suction-side leak, not a filter problem.

If your filter bulkhead leaks, water comes out. Air does not go in.
