## Questions & Answers

**Q: Why have a brass shank? It cannot be held when tightening the pipe joint. It still has to be tightened against the seal/ rubber seal friction.**
A: so that it does not cross thread

**Q: What is the diameter of the threaded brass shank**
A: Threaded brass shank is 1/2”.

**Q: Would this be suitable for a modern macdee cistern the valve bad design isnt working right. thanks for any help**
A: Might be a case of checking the height of your old one against. I'd think you could use any type of fill valve if you had space in the cistern. But same as Dennis, not sure. I replaced a terrible cheap fill valve with this about a year ago and it has really made the difference (15 minute refill to less than 10 seconds).

**Q: What water pressure does this product handle please?**
A: The water pressure recently tested at my property is 9 Bar and I have had this in over 2 years with no problems but the Armitage Shanks model gave me a lot of trouble.

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!
