The macerator is driven by a pathetic flimsy drive belt, on plastic pulleys. I learnt early on that you cannot put anything other than human waste and a small amount of toilet tissue. Anything else will break the belt and requires a complete strip down. The parts are not cheap either. I have just replaced my third unit with a cheap electric toilet from Force 4. It isn’t a branded product but the macerator is directly driven from the motor, the flush is push button and you can flush for as long as you think you need to empty the pipe. It is no more noisy and roughly half the price. I’m very impressed. I can’t recommend the lite flush as I don’t think it is up to the job.
    I had a Lite Flush for close on 10 years and basically agree with most of what you say. Mine had the original plastic pulleys but in all that time I never broke the belt or pulleys, used by two people for half of every year. The biggest problem with it to my mind is the low flush volume, aimed at holding tank longevity, at the cost of calcification of the joker valve and toilet loop. As the toilet has aged calcification of the impeller and pump discharge volute has also become a problem, despite regular treatment with hydrochloric acid. I have stripped the unit down to the last component countless times and can change a joker valve in 5 minutes without spilling any water! The flush pump O-ring seals are also very poor and cannot be bought individually, requiring some inventiveness.

    This season it became apparent that the impeller shaft seal was leaking and some seawater was finding its way into the bearings, producing interesting noises during operation. Removing the bearing on-board looked highly problematic, so I enquired about a replacement pump and motor, which is the smallest component sold by Jabsco. The cost was almost twice that of a new manual toilet, so I binned the Lite Flush. The Twist and Lock is not so convenient for arthritic hands but enough was enough.

    Thank you for that info. Changing one of our heads (the one guests use) for a Jansco Lite has been on my list for years - and the low volume of water used seemed a big plus. It’s been hard persuading guest to flush just enough to cleanly clear the bowl and not a drop more.

    But although I’m fine changing joker valves quickly and pipes every couple of years I don’t like the sound of all that maintenance so will drop it off my list.

    Thanks for the interesting feedback.
    Is this the force 4 head you fitted?

    I can't find any videos to assess noise levels but I like the direct drive and the button press flow control.

    Limited reviews.
    Has anyone else used this product?

    Thanks

    Yes it is. I can’t vouch for its durability because I only fitted it a month ago but it has kept the wife happy. No noisier than the lite flush but does take up a little more room. Be prepared to fill the old fitting holes though because they don’t match the jabsco pattern. Despite being unbranded, I am really impressed so far and have high hopes for its durability. In any event it was half the price of a lite flush

    I hope you fitted hose of the utmost quality and impermeability since you’re using it as a holding tank

    I change it fairly regularly to avoid smells, quite a quick job now, but am buying butyl pipe this Winter to see if it lasts longer. Much better than full flushes followed by an overflow over the swimmers after a couple of days of 4 people vigorously flushing,
