Excellent product and a great price in the sale. I'm replacing the old ballcock type in our guesthouse when the seals fail and a flush sounds like a foghorn. I've fitted 4 so far and they are great.

help.

Having never installed a fill value before I found this super easy. The instructions where simple clear and easy to follow, job completed in no time.

Had to buy complete unit instead of a 2£ washer. New one still leaks around filler into tank. Takes along time to shut down, dribbling from inlet.

Asked for spares they are not stocked. This item maybe superseded. I have made equiries with Fluidmaster for spares? And they have yet to reply. (5days and counting)

Makes the job simple

Takes the risk out of installing a new fill valve. Putting a metal nut onto a plastc thread is always risky especially with some modern toilets where you have to do it by feel. The brass shank solves that problem. I dont fit anything else.

I purchased the first Airgap 6000 in early November 2023, that one broke at the plastic arm at the top, I have just had to replace the replacement Airgap 6000 with another type because that one was sticking and only letting a trickle of water in the cistern my third a final one is not a fluidmaster..

Great Value and fixed the Syphon Valve also!!

Great bit of kit I had to use one as it was a blind fit so a plastic thread crosses but a brass thread is so much better and sealed first time

After 10 minutes of testing the top popped off causing the water to spray upwards, also makes a loubd click when it starts

Does the job nicely.

Average DIYer and after watching the relevant youtube video/s, fairly straight forward to install and set up. Seems robust and not overpriced. Very pleased with the purchase.
