Plastimo toilet not flushing

[bikerbill]

Hi all.
The Plastimo toilet on the new to me boat, is not sucking in water nor flushing. I checked that the seacocks were open, and moved the dry/wet lever. If the toilet is not used for a while, is it necessary to prime by filling the bowl with some water first? I am a bit reluctant to strip it down in case it's clogged with poo :disgust:

Do you means Jabsco? If so, you will probably find that after a period of disuse the flap valve at the top will stiffen up and fail to drop when the toggle is moved to "wet". Vigorous pumping may get it going again, otherwise it may need changing. It is best to leave the pump in the wet position.

If in fact a Jabsco there are some instructional videos at http://jabscotech.com/

If a Plastimo sorry cannot help... don't remember anyone ever mentioning them before. There are two current models. one with a Sealock pump, presumably a similar idea to the Jabsco "Twist and lock", and one without.
Also some older models.
I guess spares are available for the current models but possibly not for the older ones. So if an older type Plastimo replacement ( with a a Jabsco) might be not far away.


Marigolds on, together with clothes peg on nose, and get stuck in there!


Edit : ITYWF that the Plastimo toilets are the same as the RM toilets. Google will find inf,o including spares list, on them.

Thanks for the replies :encouragement: Looking at the Jabasco links, I now know what some new spares that I found are as they look exactly like some of the components from the pump assembly. Lets hope it's a clean job to do

+1 for the vigorous pumping first.
My loo needed 50 plus pumps before working perfectly last visit (after 5 weeks with sea cock shut).
First time its done that- (note to self, buy marigolds...)

If it is a modern design with the seawater inlet valves on the top of the pump there is no risk at all to the faint-hearted, so leave the Marigolds alone. Remove the valve cover which will reveal the rubber valve diaphragm. It will probably be obvious if one of the valves is salted up but if not make sure they are free to move, particularly when replacing the cover. While you have the cover off pull the piston out to check that the O-ring is in good condition, lubricate with a smear of silicone grease if you have some, or cooking oil if you don't. Your troubles should then be over.
