Hello all. I just bought a house with an inground pool in VA. The
pool guys opened it yesterday and gave me a very brief overview. I
was told my DE filter should have a pressure reading of 10-12 psi.
high pressure mean back wash and clean out traps (skimmer etc).
Everything ran well, at 12 psi, while he was here. After he left I
began leaf extraction, vaccum, etc etc. Everything was going along
fine until I noticed the pressure was high and I couldn’t get it
down. I back wash, clean out skimmer etc but when the pump starts
it hits 12 for about a minute and then, when it sounds like
everything is in full swing, it kicks up to 20. I also hear some
sharp “pinging” on the top of the metal, upright, DE filter. Is it
possible I have so much dirt in the filter from a days worth of
cleaning an admittedly dirty pool and need to “clean the fins?”
Also, just to cover everything, I believe a couple of 1 inch clorine
tablets fell into the skimmer without a basket, meaning they would
be in the line somewhere. I cleaned out the secondary basket by the
filter and found only leaves, so the clorine must still be in the
line.
Lastly, the pool is green, it’s 25,000 gallons, in ground, we put 16
packages of shock in it, (pool guy said usually we needed 4, it’s
dirty). So, the questions. Can I run the filter at 20 psi? Is my
pressure problem comeing from the clorine tablets? Dirty filter
fins? How long will the pool be green?
thanks Everyone!!!

if pressure is increasing and your pool is green, it is most likely
dirty. I would start with a clean filter from the beginning. After you
clear the pool, you will need to break down the filter and reclean
because the grids will be all green as well. When pools have an
obstruction in the suction line, this symtom is a lower than normal
pressure reading. You may also hear the pump screaming or sounding
louder because it is cavitating or not getting enought water for it too
work correctly. Lastly, there is no presure reading that anyone can
tell you your pool should run unless they know your pool. I am asked
this question all the time. There are too many factors involved to say,
such as plumbing size, pump hp, filtration type and size as well as the
length of the plumbing run from the skimmer to the filter. I always
record readings after a filter is freshly cleaned and use that as a
baseline for that particular filters normal pressure reading. Some
filters run at 20 psi perfectly clean because of the enormous pump on it.
