Rapido waste water tank


Recommended Posts

The waste water tap on my Rapido 963F motorhome has separated from the valve. Does anybody know how it is connected as it is impossible to see or access it. Need urgent suggestions as due to go away soon and the suppliers cannot fit us in! Can I fix it without having to drop the waste water tank? Help. . . !

I'm not familiar with the 963F, so can't offer practical advice.


I believe the Rapido 963F was marketed from 2004-2007 using a Fiat/Al-Ko chassis as the base. I expect all 963Fs had the same waste-water tank draining arrangement, but it might be useful if you can provide the year of manufacture of your motorhome just in case there's a difference.


This is an earlier Rapido-related forum thread that suggests Rapido may use a 'slide valve' to drain waste tanks (but that might not be so for your 963F).




As you are in a hurry I suggest you contact a Rapido dealership for advice - Wokingham Motorhomes or Highbridge Caravans may be able to assist.






You could also try copying your inquiry to the Motorhome Matters forum, as this should give you a larger audience.

My last 'van was a 983F.


If the arrangements on yours are similar, then I suspect this may not be an easy job.


The waste tank on my 'van was mounted in an insulated box, which was heated by the blown-air system passing through it.


I never had reason to check, but the Rapido documentation strongly implies that the valve is actually in the (heated) void between the tank and the insulated outer.


This would make sense, as the "tap" on mine simply rotated a rod that passed through a metal collar on the outer box, and ended up I know not where.


If this is the case with yours, then I suspect something may have broken or separated within that void.


Whilst it was (theoretically) possible, on mine, to access the inside of the tank by removing an inspection flap from the underside of the boxing, and then removing an inspection cover on the tank, the latter defeated me (and as I was only attempting a bit of cleaning, I gave up).


It would appear to me that you may need to access the void between the tank and the boxing, and on mine, at least, there was no obvious way of doing so - which leads to the conclusion that this is probably done from the top - which would mean dropping the tank. :-S


(It might be worth trying Wokingham Motorhomes for a quick bit of advice - they have a very good reputation for service on 'vans bought from them, and good knowledge of the product, but requests simply for info appear to have met with mixed response).

Thank you for your prompt reply! Alas, I think my concerns seem to have some foundation. If indeed the valve is inside the insulation, that might explain why I cannot seem to locate it easily through the very small hole in the garage bulkhead.


I have contacted Wokingham Motorhomes and they have offered some advice, but not really from a position of knowledge, more guesswork. They have, however, said that they could accomodate me for a repair next week, which would hopefully answer my urgency problem assuming that no parts are needed.


Hey ho!

Thanks for your very prompt reply. I have contacted Wokingham Motorhomes and they have offered some advice, and the possibility of looking at it next week. Whether they can fix it or not in time, i wait to see!

Given what Robinhood has said, is there perhaps another removable 'hatch' in the insulated box that encloses the waste-water tank and that would allow access to the drain valve assembly? If I remember correctly, these Al-Ko chassis Rapido models did not have a double floor, which is why heating was provided for the waste-water tank.


Assuming Rapido fitted the waste-water tank to the chassis and then fitted the insulated box around the tank, there'd still be the need to connect the operating rod to the drain valve and (logically) the simplest way to do this would be to have a removable section in the insulated box that could be replaced after the connection had been made.


My Hobby has a thick insulated floor and access to the drain-hose connection to the shower-tray's outlet is gained through a hole in the floor beneath the shower-tray. This hole is covered with a piece of plywood screwed to the floor and painted to match. It's not a subtle soulution, but it's simple and rational and might be the type of approach Rapido has adopted.
