Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

After having to replace several plastic bits (due to what has been said) and service kits on my ITT/JABSCO toilet within 2 years of buying my used boat I realised that for not much more money I could have replaced it with a new LAVAC So I did and after 5 years with no extra costs I am more than happy /forums/images/graemlins/smile.gif

Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

OK Jabsco have a few probs but apart from the self tappers I have had few probs.You need to file just enough off the nuts hexagon bit that goes inside the recess to enable the threaded bit to go in.The other thing I,ve found that when you tighten do it like you would a cylinder head,ie start at middle and work out but dont tighten fully work gradually by keep going over them.
 
Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

I've tried filing down the internal pillars as I did notice that the force of tightening the screws caused the plastic to splay out - and a bit of clearance seemed like a sensible idea. Maybe I didn't file enough off - indeed, maybe that's the whole problem?? I always have tightened them in sequence, like a wheel or cylinder head yet I have always had the problem.

Jim,

Say you are taken out into the bush in the Kruger National Park, and come across this massive animal, 3m tall, and around 7 tonnes. Grey, and having a long trunk. Is it wrong to allege that it is an elephant on the grounds that you might be mistaken and it might be a wombat? Or is it a reliable defence that wombats are usually somewhat smaller and seldom to be seen in the Kruger Park?

Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

No offence taken, Jim /forums/images/graemlins/smile.gif I knew what you were getting at but I decided to live dangerously. They would have a lot of trouble in refuting my allegations, methinks. There is a lot of prima facie evidence to support my allegations....large numbers of people all struggling with the same problem, problem known by MD,...ongoing problem over many years, significant losses incurred by customers forced to by yet more defective product. I think that 'crooks' sums them up quite nicely.

Richard, I seem to remember you saying that you'd fitted one (or two?) electric adaptors for Jabscos and you did not get on with them? What was the story? I can afford the electricity without any problems and we have an en-suite for night time visits so noise might not be a huge problem.

David,

Firstly, the conversion costs about £200, (or possibly £300)!!! I spent £300 to keep Janet quiet/happy/whatever.

Secondly - the noise is horrendous... after I bought the kit, but before I had it fitted, I read lots of posts saying "DONT BUY ONE - THE NOISE IS UNBELIEVABLE", or something like that - and now I would agree - you can hear it down the pontoon, and I am always concerned that we are waking the neighbours... I wont use it at night in a marina.

Thirdly - after only a year of use, the cork gaskets have given up.... we started getting a bit of a leak, which I thought was seawater from the inlet, then the leak got bigger, then it changed colour - you dont want to know.

I am somewhat angry - perhaps we spend a bit more time on the boat than many people, but it has hardly been used for No. 2's, (only when we're at sea plus the very occassional emergency in a marina), mostly No. 1's

I'm going to have to buy a service kit, (probably 2, so I have a spare one), or just the gaskets - who knows. And then I will find out if there are any design faults with the electric one.

Anyway, at the same time, the other toilet, (manual), started to leak from around the handle, and the original manual pump, (which I replaced with the electric), also leaked at the handle. We were in a right mess, having to work around the problem - It reminded me of the joke "What have you got if you've got an estate agent up to his neck in sh*t?" - "Not enough sh*t!!".

Bought 2 service kits in Riposto, (ripped off well and truly, but not much choice), fitted them .... same problem as you with one of them, so put the old seal back on... the other one works, but I'm having trouble with the inlet pipe which was modified to fit the electric conversion.

I wouldnt buy the electric conversion again - and Janet agrees, (based on the cost, rather than the noise).

Then that supports the allegation that they are elephants, not wombats?
 
Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

A generous smear of silicon grease round the seal before tightening down (don't overdo it) solved the problem for me.
 
Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

I used Vaseline, which Jabsco recommended in the instructions and should have done the same. I think it must be a tolerance problem - the pillars need to be filed right down to give decent clearance.
 
Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

I eventually became so fed up that I bought a Lavac. Fitted in same space, properly engineered and, so far in six seasons, trouble free. I did the swop whilst on a swinging mooring in Scotland and, unfortunately, the old toilet slipped out of my hands as I was lowering it into the dinghy for careful disposal ashore and now sits somewhere at the bottom of Loch Harport, no doubt with its own little ecosystem - probably the best use for this rubbish.
 
Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

I have always found the self tapping screws fail to get a seal so drill through and use appropriate metric stainless bolts, washers at top and nuts below. Slight sideways drilling at centre holes necessary to get the nuts to go into the recess without filing down.
Westerly Owners magazine highlighted a problem of crevice corrosion at the seal position on the shaft, which can be solved by using a bronze shaft. The shaft has corroded after 17 years satisfactory use, only because the heads has been unused since launching in April.
 
Re: Self-tapper into Jabsco toilet plastic has stripped \'thread\'

I am told that johnson pumps to a Loo that is completly compatable with the jabsco (part compatable) I need to replace my cracked vitreous china bowl thats why I enquired with johnson pumps

Have a look here

They also do an electrical conversion kit here

I converted one some years ago made by TMC (Taiwan Motor company) very noisy and slow flush water.

Hi Lemain
No specific Problems I had the Usual struggle to remove the old pipes ( I replaced them with new) and because of my small heads compartment I fitted the Lavac on a slight angle to the door and had to find a place for the Henderson pump but it was only a half day job all together and apart from having to fill in one bolt hole on show after the jabsco had been removed you could not tell it had been changed
