Proven Design PHII and the PHEII line of manual and electric toilets have a long standing reputation for their reliable, efficient operation. Conversion between manual and electric operation, whether upgrading to electrical flushing from a manual Model, or in the case of momentary power loss, is quick and easy. Recent improvements to the cartridge seal, air vent, and discharge assembly have positively impacted the PHII and PHEII's installation, maintenance and overall performance. An added benefit of the design is the ability to readily convert between left and right hand operation. (Electric motor models provided with hand lever in case of power loss.) Available in 12, 24, or 32V DC.
