does anyone know how the joints on pipes a Carver heater come apart? one is obviously the quick fit type of thing but the other seems to just go round and round as if its just pushed in ...not very good description i know but knackered after taking floor apart on van just under the heater..thanks
There is a locking ring with a collar in the fitting, when the fitting is pushed on and if you try and just pull it off, the ring and collar will stay put and lock the fitting on to the spigot on the cascade.
To release the lock and remove it then, you first push the fitting further on which pushes the ring and collar back inside the fitting releasing the lock, now hold the collar inside with your finger tips while pulling the whole fitting off.
Some Whale made white plastic fittings have a red or blue safety cap over the collar, on these there's a couple of small gaps to use a screwdriver to lever the cap off and expose the collar
Thanks for that Gary, yes i know what you mean but the other pipe does not have this connecting method ,this is a right angle bend fitting one side has the ring and collar but i cant see how the other pipe is connected to it
The 'why' is to stop a possibility of a pipe coming out in certain circumstances? (as supplied BTW they have a cap on both end).
What Whale found was if a fitting is used or pulled tight up against say a bulkhead for instance, then the bulkhead could push and hold the locking collar inside in the unlocked position.
Then with a bit of heat and or pump pressure the pipes now free to blow out of the fitting with ensuing flood!!
Sounds a bit one in a million but it actually happened a lot so they reacted and came up with those safety caps
