Pretty sure material is poly based so not sure if epoxy will work.

I have two Raritain heads, one in steady use for 12 years now and still going strong.
my recommendation is check out raritain engineering site and order the replacement part and your back in business. Coat a few dollars but substantially cheaper than new head, and be a shame to swap out for a cheap weekend head.

I hate the PHll heads, but we use ours every single day, not just now and then. Both ours cracked at the pump/exhaust hose junction and that requires a complete pump unit for replacement, nearly the price of a new head. I chose to replace the pump on one with the Jabsco electric conversion which solves the problem permanently and will do the other when I find a good deal on another Jabsco conversion or find a Wilcox/Crittenden Skipper head; now that was a great marine toilet!
I did try to repair one, but as mentioned nothing will stick to that plastic and even when I melted the same plastic as a repair it just recracked.

Being using ours daily for 5 years (perm liveaboards) and only repair has been replacement of jocker valve. Cracked pump housing usually from frost damage or overtightening of screws holding jocker valve and outlet bracket.
raritain provides bare pump housing, no need to by complete pump.

Not too much frost down here in the Caribbean. Last I checked the pump housing was around us$170.00, not all that cheap. No screw tightening will crack the housings at the base under the outlet fixture. The outlet design does not allow for the newer less flexible hoses of today, as mentioned above.

Pump housing is $68.13 at the Raritain parts harbor.
we use the optional 90 degree outlet which rotates and helps allieviate san hose stress.
i have over tha past 20 years worked on many jabsco heads and found designed and construction substantially weaker than the PHII. This year added problem, their jocker valve replacements leak like a sieve, to the extent I use the PHII jocker for folks I help.
we have many libeaboard cruisimg friends which swear by the PHII. Jabsco's twist and lock a great economy head very suitable for casual sailing, occasional overnight.
Not a good option in my opinion for consistant use.
