Use only DOH approved sewage pump basins.

We recently learned Liberty Pump Basin packages include a pump and a basin. The pump basins aren’t on WA State Department of Health’s (DOH) List of Registered Sewage Tanks.

Please refer to the List of Registered Sewage Tanks when you select a pump basin, as the list changes regularly. We are currently unaware if TOPP Industries plans to apply for registration for Liberty basins.
