The house was built in 1965, 3 bedrooms. It's in North Little Rock.
They are having it pumped tomorrow and I asked if they could ask the pump out guy how many gallons he took out.
I might call the county when we get there on the off chance they might have septic records.
Good plan. But again more frequent dumps.. will be easier on the septic
Of course this can cause issues LONG TERM with the black tank or so it is believed.
Short term I (3 months) I don't think it will be a problem but once you pull out Dump a full tank at a proper Camp ground type dump station... Even if it's mostly water. Then do the Calgon/Dawn and water thing and dump again many miles down the road.
If the access is an opening such as a concrete cover, he'll be able to see how full it is but, if it's working properly the liquids will be up to the level of the outlets running to the leach field so in essence, it's always "full".
When my parents had a new house (With a new system) built the leach field was about half what the size it needed to be and as a result problems developed..
Though I can't remember faces and names to save my life my GEO memory is .. rather good. (usually) I only have one or two things (large field of identical stuff) where I use GPS to track.
My dad and I disagreed as to where the pipes were but he was having no luck.
So I took the shovel .. He was only off by a foot or two.. Dug straight to the pipe.
And thus the problem was dealt with (Doubled the leach field size).
I told him where to dig. Ah. Geo Memory can be good.
Now days those things are "Not my problem" (One of the joys of living in an apartment is all the home owner issues that are very simply NOT MY PROBLEM.. Snow removal, Mowing, Roof, Appliances (major) including water heater, Plumbing.. NOT MY PROBLEM. Roof. Walls. Electrical.
