Hello, new to the group and I really could use some help. About two
weeks ago I was adding a chlorine generator to my above ground pool
system. I closed the valve body while working on it and when
finished, I forgot to turn it back to filter. I ran the pump for
about an hour until it finally blew a hose connection. I replaced the
hose connector but now I lose power when trying to vacuum the system.
My pressure drops from 90 to about 40. And when vacuuming up the
algea, I get green discharge back into the pool. Have I damaged the
valve body or the pump/impeller unit? And how can I be sure. Is
there a test of some sort that can be done to verify the problem.
Thank You for your assistance, I look forward to sharing with others
when I can.

Thanks Peter: I did take take it apart for a look and couldn’t see
anything, so decided to just replace the valve body. Now I have a new
valve body but the same problem. My bad on the pressure readings, they
are 12 psi without the hose attached and it drops to 6 psi with the
hose attached (wearing my reading glasses helps a lot!). The previous
numbers I gave came from the metric side of the scale. The pressure
readings have always been in the 12 psi range since the system was
brand new, so I never considered it a problem. It is only recently
that it started to drop when I attach the hose. Impellar maybe?

if the problem is only occuring when you use the vac hose, then it is
some type of suction side leak or your pump is cavitating. but if
you’ve vacuumed before without the drop in pressure, then it is most
likely a suction side leak. Is there a 3 way valve in front of the
pump? Many places to check for the leak. valve cover o-ring and/or
lid; pump inlet plumbing; pump lid/o-ring, seal plate seal; pump shaft
seal. pump shaft seal is the hardest to check and replace. if you see
any wetness underneath the pump, especially where the pump and motor
meet, that is a good possibility.

That’s just not right… you do not need to replace sand every year. It
ought to last at least 5 years, if not significantly more. Better yet
is to use a zeolite product rather than normal filter sand.
