"It appears to be a copy of the old Torbeck or Armitage Shanks quiet valve. They are supremely silent in use, and I was very happy with them in their day, but prone to clog or jam from grit or limescale particles in the water. With practice you can dismantle, clean and reassemble correctly, but the newer Fluidmaster models, though bigger and more expensive, do seem to be better."
"I have two of these fitted, and both have the water leaking from wrong side of shutoff problem. When they work properly, great, but more often than not they don't. Great value though, you get what you pay for!"
"Fitted this side entry valve to replace an "old fashioned" ball valve however it failed to shut the water off when operated. Took the valve apart but could see no obvious problems so took the part back and got a refund. I should have bought a fluidmaster as I have used this make in the past without problem but it was out of stock at the time so went for the cheaper option....wrong!!"
"Replaced a badly scaled old ball cock on a filler tank with this device feeling I had updated the installation. Unfortunately it is very noisey. I originally fitted the "HP" insert but the fill was too slow. I then fitted the "LP" insert and the fill rate is good but the device is noisey and creates banging in the pipework as it operates. It also whistles as it opens and shuts off. I intend to replace it with a traditional ball cock as it will be quieter."
"Says for toilet cistern or storage tank. Should imagine it's ok for a toilet, but with a reasonable size storage tank it is psss, psss, filling all the time even when we're not using water, it doesn't close off for ages, is noisy and now I've got to replace it. Not happy with it at all ."
