## Questions & Answers

**Q: I will also need the jhonson automatic float switch model 3615 for  the jhonson pump cartridge model 28512**
A: If you are trying to make a automatic bilge you will need a float switch and the housing. If you are replacing a automatic pump that already has the float. If the float still works you just need to change the cartridge if the pump was bad

**Q: Can I put a 1000gph cartridge into a 500gph Housing?**
A: I would call Johnson Pump a bigger housing may be required.

**Q: Does 28512 Johnson Pumps of America Cartridge replace a 2851 cartridge?**
A: It may replace it. When I was unsure I called Johnson directly and they were very helpful (847) 671 7867 is the number for them

**Q: Can I put a 1000gph cartridge into a 750gph Housing?**
A: I would recommend using a Johnson Pump 28572 for the 750GPH.

    Quality that Works
  

*by H***8 on Reviewed in Canada on 29 July 2023*

These Johson pumps are great. Once mounted, should they fail, the cartridge are a simple twist out + unplug.  My 2008 Lund bilge pump was intermittent  + weak. Picked up the 1000gph to replace it. Perfect fit, crimped on 2 connectors, twisted the old out + new in, done. 100%!!
