One odd problem I had with my Flojet macerator pump after having it for just a year, was that it would shut off after being run for more than 10 minutes, which was not enough time to empty both my gray and black water tanks. After sitting for a few minutes, the pump would start up again. The motor was not even warm, so it was not overheating. I suspected a bad thermal switch. I dissembled the motor and found a thermal switch on the brushed end of the motor. I cut it out and spliced the leads together. Never had another problem with the pump cutting out again. (I do feel the motor while it is running to make sure it is not overheating.) I read of a couple of other people who experienced this problem, too, in various on-line RV forums.
When replacing a shaft seal like this one it is a good idea to examine the shaft where the seal rubs to see if it is getting rough or scored, which would damage a new seal pretty quickly. Unfortunately there isn't much to do if it is scored; it might be possible to polish it up with very fine sandpaper, but any more involved repair will exceed the cost of a new motor pretty quickly. I had the thought that it might be possible to thread the inside of that outlet fitting to a suitable pipe thread size, but that would of course require having the correct tap, and the outward force from tightening in a fitting might just split the ABS pipe, Most female ABS threaded fittings are made pretty beefy for this reason.
Wow, the price of those service kits are right there at th cost of a complete replacement pump. FlowJet in my case.. Think i would just buy another pump and retain the old for for spare parts
@@LoveYourRVI paid about $75 for my Flowjet 3 years ago on Ebay. (new) She gets a lot of use and been running strong w/ no problems yet.. I am gonna order up another one for a spare just in case.. The only difference between the one you show and the one i got on Ebay, mine didn't come with a trigger switch. Although i made one for about $5 bucks with a heavy duty rocker switch. BTW,, you were in my hometown last month (Ridgecrest).. Almost made a trip up to the Pinnacles to say Hi but got busy..
Great deal! Usually for that price you don't get the Flojet brand. Lots of knock offs out there now usually with less powerful motors, lighter weight hardware and thinner wiring. The Flojet does up to 16 amps. The knocks usually run around 10 amps so they can be powered by a cigarette style 12V auto socket. I'm reviewing one of those right now just to compare. Works but doesn't seem to have as high of flow and lifting power. Cheers! Ray
Defiantly branded as a Flojet. Wiring is 10 gauge out from the motor.. I've used the heck out of it for over two years. Here at home i have to pump up a hill, bout a 4 foot incline and through 50' of hose to the sewer chute. Never had any problems pumping.. Also use it to pump into a dump tote in my truck bed while dry camping.. Never failed me once.. I would defiantly not be afraid to purchase the $80 version off ebay.. I just ordered another one for a backup.. ..
@@cvobiker I had a look, and many sellers are calling them Flojet in the descriptions, but they aren't the actual Flojet brand from Xylem. So that is why they are so cheap.
Nice, I didn’t know you could rebuild them.
Nice job, thank you for sharing 😊

Thanks for the tip, I'll keep that in mind if I run into that problem.

Good advice. It looked nice and shiny. The seal seems to be a thing that naturally wears out. I'm sure the hard desert water speeds that up.
