I have a 1200 gallon wastewater aerator plant, with an attached gravel
upflow filter. I have the tank pumped out every 3 or 4 years, and at
the same time, have the gravel filter backwashed.
I would like to backwash the gravel upflow filter myself every six
months, but I don't know how to do it. Surely it doesn't require
pumping out the main tank! But just what does it involve? The
aerator companies want you to have authorized service personnel do
this job, so they don't tell you how to do it. All they say is that
it is a simple procedure and should be done every six months.
I've googled this subject, but have come up empty. Also, I have
searched the web site of the company (Jet, Inc) that manufactured the
Any help would be appreciated.
