works great

Part arrived promptly and it was as advertised, coming with sealed cartridge impeller assembly, o-rings and screws (only needed one of the O-rings). Only issue was on installation, as my pump housing is horizontally mounted. Found it difficult to properly position the o-ring on installing the replacement cartridge, as it kept leaking. It took a number of tries before I was successful, the trick being to use o-ring lubricant and first mount 34;without34; the motor assembly. Once the impeller and o-ring was correctly positioned and screwed into place using the original short screws and only the metal cover plate (no leaks under water pressure). I was then able to install the heavy motor piece by sequentially unscrewing the shorter screws, which kept the plate and impeller parts in place. Used the longer replacement screws to fully attach the motor assembly. Again, it was a little tricky but doable. My pump has been running great since replacing the cartridge assembly and it was much cheaper than hiring a plumber to replace.
