discovered that the manual pump on our toilet (sealine S23) is failing to flush at the weekend.
Did take it apart and have a look but couldn't see anything to obviously wrong with it (but wouldn't really know what to look for anyway).
Is it a case of just buying a replacement kit and if so, does that just contain new rubber gaskets etc?

any other causes / fixes to the problem
 
I agree to check the flap; that was the problem on mine. I found that it is best to leave the lever in the wet position (after flushing and drying) as them the flap is not under tension.

do a search " headmistress" there will be the answer. ( its prolly the flap operated by the little lever )

Yep - or the 'joker' valve.

Buy a new pump. They cost about £30 and can be changed in about 15 minutes. Don't bother with the 'service kit' unless you have plenty of time on your hands.
 
I agree, leave the switch in the wet position to stop the useless rubber flap getting bent.

And if the lever has been left in the dry position and the toilet pumps out but not in, try flicking the lever to the wet position and try again later. The rubber flap usually loses its bend after half a day, and then works again.

Agree with the new pump suggestion - after using service kits several times, a new pump becomes a "no-brainer"

I have found that new pumps cost about £60, and service kits about £30, (or £70 in Sicily!!).
 
just made a couple of calls and it seems that £60 is the going rate and not £30.
Would this definatley solve the problem then - not likely to be another cause elsewhere, as don't want to fork out the money and it doesn't do the job
 
The pump is an expensive option unless its broken. Just get the service kit and if you haven't done one before, take some photos as you take it apart. The culprit is almost certain to be the rubber flap at the top.

BUT. Be careful when you refasten the top of the pump, because if you overtighten the screws you will break the mounting and that WILL mean a new pump (you can then save the service kit for next time). The little posts the screws go into are made of something with the structural integrity of Caerphilly cheese and snap off at the slightest provocation.

Cant guarantee anything from here and I suppose if the cause is a blockage in the inlet or discharge pipes, then changing the pump, (or servicing), will not work.

I guess I am saying that, if you are considering spending £30 on a service kit, I have discovered that it is better to spend the extra £30 on a new pump.
 
One of the attractions of a new pump is that it now incorporates the new style locking handle. However, they are really easy to take apart and service. Taking the inlet hose off to check there are no blockages is also worth doing.

I agree that it is really easy to take apart and service. However, I have found the success of servicing to be variable, and, when both toilets are leaking "stuff" and you are a few days from being able to buy another servicing kit, (having used the two spare sets), and SWMBO is aboard, the prospect of being able to fit a new pump would be delightful.

The problems I had always involved leaks from around the top, (which I believe is merely seawater, but SWMBO wouldnt believe me!!), due to the self tapping screws - what a crazy arrangement in something designed to be serviced.
 
Had similar problem last year - would flush but not pick up water.

After i'd dismantled the pump I realised how much of a pig they'd be to get right again with a service kit - I just bought a whole new assembly. To me it was worth more than the service kit because:

1) Takes less time, no dis-assembling/ re-assembling
2) Guaranteed to work
 
I had the same prob. last week even though my pump was replaced recently with the later spring over the rubber flap. 4screws and 2 mins. latter i found the fault to be a small strand of seaweed under the flap breaking the suction.
 
Exactly the same as alt - flash but water intake. Fitted the service kit in about 40 mins - pain but easy. Next time though I would go for the pump option, coz then its all new! Mine was the top valve knackered!
 
had the very same prob on mine over the years. undo the 6 screws on top of the hand pump remove carefully, the little rubber flapy bit is obvious. just put lashings of VASALINE on the contact points ONLY.........result LARGE HOORAA,S all round!!!!!
 
In my last boat used the service kit on an old toilet. Pigging thing would not seal when put back together. Tried a dozen times before the screw mounts broke, so then got a complete pump, no problem.
Three weeks back new boat toilet joker flap came off, couldnt get the pump so got a service kit, guess what, pigging thing has a very small weep !!!!!!!!!
IMHO just buy the complete pump whats £60 spread over a few years.

Best solution for that is to do away with the self tappers, drill the holes right through and fit long bolts with nuts & washers below
