Trooper water tank drain taps

Hello All

I`m a newbie having just discovered this site while searching for tips on this problem. Hope this site is as good as the AS service.
 
Does anyone have any tips on how to replace these taps?
Both mine need replacing but the taps appear to be secured with a nut on the inside of the tank which means the tank has to be removed to reach inside the tank through the large opening on the underside, or does it? Hoping someone has had and overcome this problem.

Grateful for any tips or replies in general.

Thanks
Mick

Hi Mick, Not sure if any one has said it but welcome to the forum, all questions daft or technical an answer will be know by one of us.

Right now regarding the water tank taps. Yes if they are like mine, Duetto, they have a nut inside. The tanks are not too hard to lower. I put a trolley jack under the support wood after a good spraying of easing fluid on the hangers.
I have heard of the threaded hangers snapping in service allowing the tank to drop. Considering the weight of a full water tank four pieces of bent rod and a lengh of plywood seems a bit crude.  They can be made from threaded rod from the likes of Screw Fix. I will check mine on my pre MOT crawl round.
When I replaced my waste tap I extended the drain pipe and clipped it to the underside of the door sill. Some sites don't have the drains very well thought out and are too far away to reach with the original pipe.
 Good luck,

I'm going to replace my waste tank drain tap on our Trident.
I'm looking at fitting Parts from CAK tanks to bring the outlet closer to the side of the van and give it a larger bore to stop blockage.

I would like to find out what size the hole for the tap is before I try and remove the tank. I'm presuming it's to accept a 3/8 BSP fitting.

 Sorry I cant help with the sizes. There was a new tap in the drawer when we bought the van. I bought a short stub with a back nut for the waste tank to match and a 2mtr piece of pipe. As I said the pipe is fastened to the underside of the sill with Terry clips. The pipe can be unclipped as much as needed to reach the drain.
So far I have not forgotten to secure  the pipe, I will cover that later.
