A relative simple task that can be achieved with only a few tools and some products from Bunnings.
Products required:
System inlet replacement kit to suit your system brand. I suggest taking lots of photos of the system and and removing the lid and take some of the internals before heading to the plumbing isle of your local Bunnings to help make the friendly staff job easier to assist your requirements.
Some plumbing tape. Extremely cheap.
Tools:
Adjustable wrench or multi grips found in the tool shop doesn't have to be expensive.
Before getting started double check the new inlet is the same as the one in your toilet or if advised it is an alternative replacement then your good to go...
Once you are home lay everything out in the bathroom or toilet area.
Have a bucket and a towel ready to catch water
The toilet lid should be removed if not remove it.
Turn off the water supply at the cock valve
Flush the toilet until no more water flows, it will not completely empty don't worry that's what the bucket and towel are for.
With the adjustment wrench or multi grip undo the first nut on the inlet pipe below the system, then undo the next one.
At this stage you can remove the inlet valve.
Take out the new one and place them side by side
Push the lock collar up so that you can adjust the height, don't worry it is a bit tight give it a wiggle and a pull, then compare and lock back off with the collar.
Remove the lock nut and rubber seal from bottom of valve thread
Apply plumbing tape to the plastic thread at the bottom, apply it in reverse rolling not standard forward wrapping.
Go to system and make sure you remove the old rubber seal and the old lock nut then insert the new rubber seal and put the new lock nut on the inlet pipe.
Now insert the inlet valve makong sure it slips into the pipe,( if like me the filter in the inlet valve stops it going down it can be removed )and proceed to screw on the lock nut underneath, nip it up with the adjustable wrench or multi grips but don't over do it.
Next screw the pipe nut up and give it a firm tighten but not over doing it you don't want to split it.
Give the pipe a good wipe dry and then turn the water back on and feel for any leak, if so turn off give a little more tighten and try again. It's also good if there are no leaks to still come back and check.
If all is good put the lid back on, clean up, give yourself a pat on the back and proceed to the beer / wine fridge.
I hope that helps someone.
