A SEPTIC TANK NEEDS TO BE PUMPED EVERY COUPLE OF YEARS – AT LEAST – TO MAINTAIN PROPER FUNCTIONALITY
You should pump your cesspool every couple of years. Put at least 10 gallons of chemical (acid) in a Precast Cesspool (*Note – acid should never go into a septic tank). Lastly, Aerate your cesspool regularly to allow it to properly drain.
Usually, when a cesspool is full the water will drain but very slowly. If the water does not drain at all then you likely have a clogged line.
If you have to pump your cesspool more than once a year it is time to upgrade to a new cesspool.
If you have a Block Cesspool from the 1930s, 40s, 50s or early 60s you should fill it in and replace it with a Precast Cesspool. A dip in your lawn is an indication that
your Block Cesspool is caving in.
Note – most houses have two cesspools. Always pump out and treat both cesspools before you replace your cesspool
