Any plumbers or DIY experts out there?
Decided to remove the cistern and clean it as it had mold in and around it on the walls. While putting it back, water inlet hose where it connects to the water supply on the wall started leaking. It is a straight hose and has a hard plastic type valve thingy no washer was there. Now, either I have damaged the hose while cleaning or doing something really wrong. Here are some pics. I have exactly same toilet in another bathroom with same hose. Even if you open the white plastic valve it doesn't leak. Don't want to pull that one apart to check else I might have two leaking cisterns. Any ideas what could have gone wrong. Thread seal tape you see in the picture wasn't there before, I put it but no luck.

I'm no plumber but I recently had trouble with our one. On the advice of a plumber friend I purchased a flexi-hose fitting from Bunnings for about $15 and it did the trick.
It has fittings at either end with washers built in, much like the hoses going into a washing machine.
I'm not sure if that is what you need but for me it was a cheap and easy fix.

Did it have metal connectors and is your cistern plastic? Yeah I think somehow the seal or the hose got damaged. It's been bugging me. Just wanted to figure out what happened? Might get the flexi hose tomorrow and give it a go. Thanks

The cistern is all plastic. The new hose is braided with metal connectors, just screw it on and problem sorted.
The old connector was some copper s-bend pipe and we had a persistent drip at the cistern end.
I tried sealing it up but my skill level must be too low.
Trying to fixing the old one was such a waste of time considering how easy installing the flexi hose was.

Will this be ok or you reckon Bunning quality will be better?

Can't honestly say, I've only ever installed a single hose and I just went for whatever was hanging on the shelf.

Do make sure you get one long enough to do the job

The water seal isn't the threads so tape there won't fix it. I've had earlier versions of the plastic pipe and the seal was the piece between the split cone and the inside end of the tap. I think it hardens up and doesn't reseal well.

So what's the two plastic bits in the picture. They go after the split cone. What do you mean in side end of the tap as I did not see any seals there?
Is it recommended to buy the same type of hose or just go for the flexi hose? I guess this was chosen by the installer as it looks better??

At each end there's only 1piece after the cone. In your picture it is the bit with the ridge around the middle. You can see where that touches the tap. In my case that bit was a tapered rubber ring. I changed to the SS flex hose because it seemed more tolerant of being disturbed.

The only advice I can offer is that which was passed down to me from my Grandfather who was an excellent plumber:

If it's yellow, let it mellow.
If it's brown, flush it down.

I trust this helps.
