After two years of complaints about the Jabasco manual head that came with the H33, I gave in. I purchased the Jabasco Lite-Flush. Main reason was that it was a direct fit for the old Jabasco, same screw holes and hose cutouts In theory you dont even have to replace the hoses. But we felt that this was a good time to do so. The only non-easy part was running the wires to the panel.
The wife is happy. Its been in for two years now, no problems.
