I've spend hours looking through various online catalogues and other sources for advice. What seems to be the most long-lasting and reliable design for systems that pump grey water from laundry tubs to home sewer systems, that do not require human intervention? (I assume that one is not allowed to mention trade names on here.)


  • Ours drained into a sump. From there the sump pump ejected it out of the house. Sump pumps are pretty reliable. We had to use laundry detergents compatible with not killing our grass. – Harper - Reinstate Monica Oct 4 '18 at 23:44
  • @Harper: Thanks! That's an idea I might be able to use. I could pump from the sump into the piping to the septic tank, couldn't I? – Bill Bell Oct 6 '18 at 14:42

Type into your favorite computer search engine like Google "sink tray system sump pump" and you will get lots of pumps and places to buy them.

  • Thanks for your answer. My problem is that I have done several searches like that and I find the range of possibilities bewildering. – Bill Bell Oct 6 '18 at 14:43
