Drop in replacement for standard jabsco that's not jabsco

I want to replace my new Jabsco Manual twist and lock (it is leaking from the bowl on a new boat; it is less expensive to just replace the whole thing than have a technician troubleshoot if the base is cracked or is it a gasket or the plug etc). I have had this toilet on multiple boats for the last 20 years so I know it well having replaced 20 joker valves and probably 6 pump assemblies.

Before I get another of the same, is there a drop in replacement of a different brand manual toilet that works better than this jabsco.

The Raritan PH SuperFlush is the current version of their tried and true PHII, which has been the top rated manual toilet pump since they introduced the PII in 1983and has a footprint that matches the Jabsco mounting bolt pattern. It's considerably more expensive, but will provide 20+ years of reliable trouble free service with minimal repairs if it's just kept very well lubricated, the joker valve is replaced annually and is rebuilt (about $60 for the kit) every 5-6 years.

Defender has it for an excellent price...the household version is a bit more. I've read they offer free shipping on $100+ orders.

They are awesome. Weíve had one for many many many years. Lube it with superlube. I used to use vegetable oil and vinegar, but the Head Mistress recommended otherwise. It does have 1 weak spot. The 1210 handle socket. Weíve broken about 1 every 10 years. Always carried a spare, and once had to use a bucket until I was able to 3D print one, then finally got a replacement. LoL

Peg, thanks again for your excellent advice. The only issue I see with this drop in replacement is that exit connector to the holding tank faces down, not out/up as with the Jabsco. Not sure I have enough extra hose. Same with the water intake, on the Jabsco it faces back, on Raritan is faces down in the front. Need longer hose.

I third the Raritan. It does have a straight discharge option if that helps:

Don't know of anything for the flush water though, other than an elbow and more hose clamps.

Discharge fitting can be oriented any direction--up, down, to either side, or replaced with a straight fitting. As for the intake fitting location, new hose is the solution. You can use Shields or Trident Flex PVC #148 (the cheapest sanitation hose.) Do not use clear water hose.

Check out the blow-out diagram from the Raritan site:

https://www.raritaneng.com/uploads/L...w-e7e702c5.pdf

That discharge flange and elbow appear to be two separate parts. I would assume that the elbow can be rotated 360 degrees. Otherwise it would make 'universal' installation a challenge.

Re: Drop in replacement for standard jabsco that's not jabsco

I'm also planning to replace my toilet (Raritan PHC) with a SuperFlush. Search the internet, as I found three suppliers selling it almost $100 less than others mentioned. One of them with free shipping. If you have any questions about Raritan's products give them a call. I did today and talked with Mac who help straightened me out on a couple items.
