Protecting Jabsco manual toilet from frost

Went to the boat today which is on the hard. Removed the toilet pump and cover plate. Then pumped out the water and wiped dry under the top gasket where some water was trapped. Must remember about not stripping thread when replacing pump next Spring.
 
You do not say which Jabsco Toilet or it's age - this is relevant. A 59218-series (Brydon Boy) were made of ABS, a 29090/120-0000 were ABS, a 29090/120-1000 were made in both ABS and glass filled polypropylene, a 29090/120-2000 and later are talc filled polypropylene ,this will all have an effect as to what you use. WhenI was Technical Help at Jabsco, I had more calls about toilet failures due to attempted winterising and cleaning than any other customer caused faults.

Remember, the golden rule is...DO NOT PUT ANY THING IN THE TOILET, UNLESS YOU HAVE EATEN IT FIRST. If you are happy eating any anti-freeze, then go ahead! Personally, for the sake of four base bolts, and two jubilee clips, I would remove the toilet and put it in the under stairs cupboard for the winter. The materials the toilets (And not just Jabsco manufacture) are made from can tend to be vulnerable to chemical attack. I received one toilet, returned from a customer, that had been cleaned with a common weak household cleaner that had reduced the toilet to a powder!!!

I would guess, but I wouldn't want to test it, that if your toilet is a glass filled, or talc filled polypropylene you may be OK.

Some customers I spoke to, just replaced the toilet every year!!

We'll you obviously never needed to speakable to me, and are, possibly, one of the lucky or careful owners - however, do you not think you may just of tempted fate with that statement. I can assure you, that for at least 4 hours of every working day, I was talking marine toilet failures with endusers, and few were down to product faults, most were down to installation, cleaning and winterising in that order!

OK, that means it is a talc filled polypropylene, you should be OK with most chemicals for the structure of the head, but, if you decide to try antifreeze, also check the compatibility with neoprene, and brass (Which is what the valves are made from)

Excuse my ignorance, but, what is too hard about removing it, and storing at home?
