How to remove Reich elbows on Hymer Water Tank

[OldAgeTravellers]

Hi all,
We woke up this morning to no water pump working in our Hymer S class.
I can hear the pump running but slowly so it may be kaput or just blocked with debris.
I can't get the pump out of the tank without releasing the blue Reich push fit elbows but can't find out how to release them. I have tried pushing the grey ring and pulling it but no movement. Anybody found a way. I can't
Cut the pipes as there is no slack.
Suggestions please.
Steve

This might help...

I think it is meant to lift out of tank for replacement. (If its like mine) ' Why won't it come out ?

Thanks @Barclaybasher & @Figaro for the help, I finally managed it with two flat screwdriver bits forced in underneath the release ring so as to release it evenly. The pump wouldn't lift out without because the pipes were not long enough without kinking the ridged pipe to the pump.
It appears that the pump is nack***d so cannot produce enough pressure to get to the taps. I had intended to buy a spare when I next come to the UK but now unfortunately it will probably be a very expensive distressed purchase.
Oh well, that's what money is for. I suppose.

I once had a Reich 19L twin impeller pump (shown below) which I thought was duff. As an experiment, I swapped the blue and brown wires at the joint nearest the pump, and away it went for several months later. These days, I always carry a spare.

Cheers,

Jock.

Don't wanna add to your whoes my friend , but i concluded they ent supposed to come out . I had issues with my water pump last year (year 2000) . I had discovered my elbows leaked the year before , so when my water system went for a burton i decided to sort that out at the same time . Now to cut a long story short here , my pump packed up due to owner abuse . The original problem was elsewhere , but still the pump needed to be replaced . It came out okay , as it was connected to the elbow by way of a jubilee clip , but i also noticed one of the elbows had considerable sideways play in the plate to which it was fitted . I elected to purchase a new plate with the elbows already fitted , and when this arrived , neither had any sideways play in them . All fitted and working , a couple of days later , i was finally leak free . However i decided it maybe a good idea to remove both elbows to keep as spares , and this is where i discovered that , though i could remove them , the damage done in the process could possibly cause the leak i had just fixed , so i scrapped the lot . My conclusion ! .

One final thing , check the pump itself , there are two , the difference is the check valve , and this is how i broke mine . It turns out , if you can remove the check valve , you have the expensive reich pump (think around 80 odd quid) . But if you can't remove the valve you have the cheaper pump , also a reich , it's about half that , and you get a new check valve already fitted . I had the cheaper pump , but errr , managed to remove the valve , trouble is i also removed a good portion of the pump body as well . Basically what i am reliably informed , is technically known in the trade as fubar .

Just to report back, after managing to remove the elbows to find that the pump worked but would not supply pressure. The non-return valve was a separate unit in the pipe so no problem with that.
A trip around on the scooter and was directed to a chandlers just back over the boarder in Spain, great amount of stock and unusually great prices. He had a "Rule" submersible single impeller pump with almost the same spec as the Reich one for €29 took a punt and with a bit of fiddling as the outlet spigot wasn't quite long enough but a bit of spare gas hose did it ok. Replaced the very rusty pipe clip that Hymer or whoever fitted, with a salt water grade stainless one and all is now working well.
And a lot of Brownie Points earned for being such a clever fella.
When I get home I think I will swap it out for a proper diaphragm pump to save future hassle. He had a Seaflo one there for a good price but I don't have enough tools with me to do the carpentry needed to make a support shelf in the under locker.
Thanks to all for the suggestions.
