We're putting in a wastewater system (for a 2 person household) in which effluent from laundry, bathroom, toilet kitchen will go through a septic tank then a sandfilter into a pumpwell with a submersible pump then into reln drains. The sandfilter is a secondary treatment system, so the end water should be fairly clean.
What pump should we use? How long the pump lasts and its cost are the main issues.
Someone told me that wastewater quickly corrodes pumps because it is highly alkaline. We use water frugally, and use laundry detergent, soap and toothpaste in as small amounts as we can get away with, and only occasionally other chemicals.
What would a typical pH of such wastewater be?
Do the organisms breaking down waste change its pH?
We're considering a Jung Pumpen U3KS ($239) or a U3KS Special ($279), whose seals, we are told, can withstand chemicals that would degrade cheaper seals. Both are made of plastic.
We were considering an Onga VF150 ($189), with some cast iron parts, but the rep said its seals wouldn't last as long as the Jung Pumpens.
I'd be grateful to hear your experience and thoughts, and any info about wastewater pH.

The forum has well and truly died. No one posts here any more. Try over at home one for an answer.
