I hope all so well with everyone, the plan will be to either replace the pump assembly or a new toilet but a couple of the screws have stripped and cracked the round bracket on the pump assembly for a Jabsco toilet so it was leaking but now can’t create the vacuum so won’t flush. As a temp fix how does drilling out the 6 acres and replace with nuts bolts and washers to secure it, would this work with some of the plastic upright screw holds missing?

Cheers

Not sure what round bracket you are talking about. The only place with 6 screws is the pump top cover. If its not working now and the threads are stripped, youve got nothing to lose but your time by giving it a go with screws and nuts as a temporary fix. Do not overtighten the nuts though it will distort and crack the top causing more leaks. Good luck.

I replaced the hand pump on my Jabsco with an electric diaphragm pump and a separate flush pump driven by a timer to run the flush

I did exactly that some time ago and it worked ok, I didn't actually crack the top cover but I really struggled to get it to seal, as mentioned above it's a fine line between tightening the 6 screws enough to seal but not too much...

I used to buy a new pump every few years, I found it easier and not a whole lot more expensive than faffing around with a spares kit but I've gone electric now

We also tend to buy new pumps in the sale and replace the whole pump every 18 months or so as not much more expensive than buying a service kit at full price - and massively quicker / cleaner.
Absolutely no intention of fitting electric pump. No need and more noise in the night.

Once you think about going electric I suspect lots of better brands out there than jabsco but perhaps spare parts not so common. I think look at other makes if going electric -I seem to reccall some quite pricy like Tecma etc. when we replace the hoses I think it might be time to to replace the jabsco manual but not until. As said we just service currently by buying a new pump assembly but keep a supply of bits for emergencies.

Screwing into plastic needs a delicate touch. The first Jabsco on my boat had to be replaced and I found that the installer had overtightened the mounting screws and cracked the housing. Both before and after that I have take the top plate off for servicing and occasionally had difficulty getting a seal, but generally by jiggling the gasket around a bit and a little silicon grease applied got it airtight again.

Thanks all, I fitted a new toilet this morning, took off the old pump and a couple of the screws became loose so couldn’t get a good seal when I reassembled it. The toilet is 20+ years old and I think plastic fatigue finally got to it!

A right pain to remove the base plate, I think two of the screws were glued in and the other two once removed I couldn’t get a thread and spun and spun.

Only job left to do with the new one is to secure the base plate with the final two screws.

Cheers
