Fluidmaster PRO45B Fill Valve with Brass Shank - Black

Great quality and price, and I fitted it in no time – no plumber needed.

Great product and easy to install

An old ball valve wouldn't stop dripping even with washers replaced. Decided to replace with this newer valve system instead of another ball valve. Once installed have no probs...& it's a lot quieter! But installation didn't go without its problems...because of existing setup as opposed to fluidmaster. Firstly the original plastic back nut to be removed from sistern was a large hexagonal shape and full of old gunk along the thread. Too big for normal spanners to remove and too confined for heavy duty stuff to get a grip. Got around this by placing a chisel on the left edge of the nuts flat surfaces and hitting with a hammer..it soon started twisting free! Once I had the fluidmaster in place I found there was very little room for manoeuvre...I positioned the narrowest part of the float away from the cistern wall with millimetres to spare...which led to the u shaped wire hook in the toilet handle lever catching the floats mechanism when pulled. Hacksawed into it untill it was easy to bend inwards with pliers. I never bothered replacing old fibre washer in the pipe connection (should do this really) but instead put a couple of wraps of ptfe tape around the copper thread of the unit before attaching to water system. Hand tighten everything it said.. Nope..turned water supply back on...water was dripping out...from both back nut and main connection. Tightened both up slightly with spanners...did the job..almost...hands slightly wet at the touch of each bolt....at intervals..wiped both areas dry with tissues...tightened each time slightly until no wetting whatsover...job done. However..the extra tightening of the main connection made fluidmaster lean to the cistern wall slightly whereas the float would now stick. Had a wooden wedge shaped dowel to hand to wedge inbetween the cistern wall & the red cap untill the float was free..applied glue around the dowel/cistern wall (NOT the red cap which might need opening at a later date). Checked the backing nut again...this shift led to some slight seepage..a slight tighten again until it stopped. Hallelujah!!! Just want add here..in my experience of changing original ball valve washer..and opening the top of fluid master for a flush/washer replacement....bath taps are lower...turning on both bath tap and cold water tap downstairs reduced water flow to cistern to zero without having the need to turn off main stop cock. (Mine's awkward to get to). This massive review was brought to you in lockdown!

Refills so much faster than the old fill valve and is much quieter. Worth the extra money vs. a cheaper alternative.

Good for the money, quiet flush and easy to fit. Fitted in 10 minutes. The only one thing is that they should of supplied a brass nut, which came with a nylon nut.

Initial impressions after a few days of installation are positive. Having had a previous inlet valve (fluidmaster 400A) replaced with a like-for-like replacement this was soon followed by water hammer, occurring when the adjacent sink tap was turned on whilst the loo was refilling after flushing. I had 5 different plumbers in to try and fix the problem. This ended up costing me hundreds as I had a new tap and a water hammer arrestor fitted. But neither helped fix the problem. Partially closing the loo and sink valves decreased the hammer but made the noise from flushing or the tap much more noticeable throughout my house. I saw the Fluidmaster 45b advertisement saying it stops or reduces water hammer and so decided to give it a go. I also viewed the fluidmaster bottom entry inlet valve installation video on YouTube, and decided I'd give it a go rather than pay another £80 to a plumber. I found the installation just as easy as the video suggested. Upon removing the old valve I noted it did not contain the small water pressure reducing 'bung' and so ensured I fitted this (supplied with the 45b valve) into the 45b prior to installation. I believe this device, along with the brass thread at the bottom of the valve is the reason why (fingers crossed) the water hammer has now disappeared whilst the refill is ultra quiet, even with all valves now turned back to fully open. If only I'd done this from the outset I'd be about £400 better off!

It is worth paying a few pounds extra to get a well made valve like this rather than a cheap model - a cheap one failed in the night after 6 months and brought my kitchen ceiling down. The bottom flange is injection moulded onto the brass inlet, making it watertight and much more rigid than cheap models. The rubber washer seals between the flange and cistern base and you can get a good seal just by turning the nut hand tight. On the cheap models, the flange is loose and the seal is made by compressing a tapered rubber washer between the inlet pipe and cistern entry hole - it needs a lot more pressure to get a seal and is prone to leaking.

The gold standard - perfection. Easy to install. Easy to swap (can just swap with taking apart). Why didn't I know about these before- Amazing

Risolto ogni problema.

Utilisé en remplacement du modèle identique, qui avait tenu 15 ans, et a cessé de fonctionner à cause du calcaire. Produit très qualitatif. Bien noter que le filetage mâle est en 1/2 pouce.

es de inglaterra, así que aquí no valen esas medidas, no son los estándares nuestros, es producida por los hijos de la gran bretaña

Works great
