The old inlet valve was leaking water into the overflow and was very noisy so I bought a new one. The Fluidmaster from my local Bunnings was easy to install and wow -
insanely quiet!!! Can be easily adjusted for more or less water into the cistern depending upon your toilet and preference, but this is highly recommended.

my toilet has been dribbling into the bowl constantly for 5 years. Must have wasted thousands of litres. Wasn't sure which part was the problem so did not know how to fix it,
Looked on you tube and saw someone fitting one of these so got one myself. Finally has stopped running for the first time since I moved into this house. Wish I had have
changed this years ago. Didn't think it would have been so easy to stop it. Cistern is an overseas brand I have never heard of before so thought parts would not be available
and I would need to buy a whole new cistern but no just a $20 part fixed it, Thank you so much bunnings great place to shop.

FIVE FAILURES

I now have a collection of 5 of these, 2 of the earlier version and 3 of the current version with the screw adjustment on the side. They all failed the same way, unable to stop
water at the top. Tried a new washer on one, also failed. Never tried the top replacement part, just a new unit each time and works a year or two and fails again. Suspect no
effort will ever be made to fix the dud washer operation. No more, will try something different.

The inlet valve works well and is easy to adjust to workable valve height. It replaced the same product which was installed 10 years previously as a new rubber seal did not stop the slow leak so the unit itself was worn. This cistern gets reasonably heavy use whereas others which are used less are still ok with only rubber seals replaced. however I suggest that 10 years is too short a time for unit replacement with mostly only two users.However the replacement unit works well so far. Even so i have recommended it to other people.

The instructions were easy to follow, I had no problems changing the inlet valve although had to call a Plumber in the screw the bolt from the water inlet on the thread beneath the cistern, turned out to be $250 to screw a nut that took one minute. I'm sure it would have cost a lot more if I did not have the part . Trick was to discard the filter , it was making the bolt lop sided and stripping the thread. Apparently you do not need the filter.

Easily fitted except instruction sheet point 5 - 7 for purging the unit for potential problematic dirt didn't work so I ignored them and continued with the installation and it worked fine. But I guess the real proof will be in the longegivity. The Caroma cistern only functioned for about 5-years before the soft silicon rubber sealing ring in the level control valve failed.,

Good product, very easy to install. Comes with instructions, but note that the Fluidmaster website also has info, and there are a ton of YouTube videos as well showing how to replace this unit. Leaky toilet inlet valve sorted in no time.

Helpful comments lead me to the right choice. The fix-a-loo popped up first, almost bought it until I saw the comments. Apparently it stops working after a while (drip comes back or really slow fill). Got pointed towards the fluidmaster and have not been disappointed. Leak is gone, fills well, no problems! Very happy.

The unit is great and compact.I have a toilet that still single flush with a ballcock and a well overdue inlet valve that dripped and hissed like a king cobra being attacked by a mongoose.I found the unit relatively easy to install except taking off and replacing the top cap which was fiddly to do once you install the unit and if you have gorilla hands like me as it requires you to hold the unit under the float to turn the top cap..My advice is to take off the top cap prior to installing.Once i had it installed it was super easy to adjust and worked straight way.Its quite quiet when refilling and the float cut of the refill it off straight away at the set level.Make sure you read the instructions first.Great product for the price.
