I bought a Jabsco/Par 36800-1000 belt drive Diaphragm pump to replace the 
original Jabsco unit on Half Magic.  Same footprint although we had to redo the 
manifold slightly to make connections fit properly.  Three times as pricey as 
the Shurflo but there was some comfort in knowing the last one took 33 years to 
burn out.   And service kits are available..

Also highly recommend the Shurflo pumps. 


And Fred — make sure it’s fused correctly :P

All the best,

Just fixed a similar problem.  Replaced with a matching Shurflo Aqua King 3.0.  
I have no problem hearing this pump.  Hope this helps.

Hi, all — I tracked down a leak in my potable water system last weekend to an 
apparent split or leak in the diaphragm on the belt-driven (probably original…) 
pressure water pump on my LF38.  I could probably find a parts kit for this 
pump; but given its age, I’m thinking about replacing it with a new pump.  I’ve 
been looking at the Jabsco PAR-MAX line, specifically the PAR-MAX 2.9 or the 
PAR-MAX Plus 4.0.  Anybody have other suggestions for me?  I don’t want a 
super-quiet pump, as I want to be able to hear it run, especially when tanks go 
dry; but I’d like something that hammers less than the original pump.
