Technical Advice - Taps and Mixers
Top trouble-shooting installation tips
Why can I get a mix of water on my BSM when I have it turned to bath but it runs cold when turned to shower? Sounds like you have unequal water pressures. Fit a pressure reducing valve to the higher pressure side.
Why does my basin waste leak? It needs silicone between the flange & basin (it will appear as if it is the plug that can’t hold water but the water is seeping under the flange and into the slots on the waste underneath).
Why isn’t water coming through the douche on my 3-hole bidet? You need to remove the perforated plate and wind up the slotted screw (wind down to reduce water flow).
My mixer tap is leaking Remove the head (by removing the “indice cap” or loosening a grub screw) then clean the seating and the rubber washers or ceramic disk valve.
Water trickles from the tap after turning it off This is caused by ‘capillary action’ and residual water in the spout is being siphoned out. It should only last for a second or two, and is a nuisance rather than a fault. If the tap is fitted with an aerator, this can be replaced with a more restrictive type to reduce the amount of water that trickles out.
Why does water come up through the pop up rod hole on a three hole mixer? Sounds like the packing nut on the spout is loose (second nut up from the bottom). Tighten it up and the problem should be solved.
Our bathroom and kitchen taps are designed to work on water pressures from 0.1 bar (1.45 p.s.i) up to 8 bar (116 p.s.i) at temperatures up to 65�C.
Note! Some models require a minimum pressure of 1 bar (14.5 p.s.i). See individual products for more detail.
Inlet connections will vary from model to model. The most common inlet connections are 1/2" and 3/4" BSP male threads, 15mm copper pipes and 1/2" BSP flexible hoses. See individual products for more detail.
All of our bathroom and kitchen taps are constructed from high grade materials. The bodies are 100% brass.
We use a number of different types of valve design throughout our kitchen and bathroom ranges. They are:
This type of valve is similar to the rising spindle type, the difference being the spindle will not move up and down when turned on or off. This type of valve and the rising spindle valve are probably the sort of valve that most people will be accustomed to.
With this type of valve, when the tap is turned on and off, the spindle on which the head is attached will move up and down accordingly.
1/4 Turn Ceramic Disc:
This type of valve incorporates a ceramic disc mechanism to control the flow that will either turn through 90� or 180�. They are quicker to operate then the more traditional Rising and Non-Rising valve designs. This type of valve has excellent resistance to wear and corrosion.
Ceramic Single Lever Cartridge:
This type of cartridge is used on the single lever type mixers mainly in the contemporary range. From the mid position the lever will turn through 45� on both the hot and cold side. These cartridges utilise long lasting ceramic disc technology and, as with the 1/4 turn ceramic disc valves, have excellent resistance to wear and corrosion.
Bristan taps are individually tested and are designed to conform to a number of British Standards including BS1010 and BS 5412. They have also been tested by the Water Research Centre and are approved or pending approval, by the Water Regulations Advisory Scheme and comply with all UK water regulations (subject to correct installation).
Each Bristan tap is guaranteed for 5 years covering all manufacturing defects. This does not apply to any products that have been damaged during fitting or miss-use. Gold and special colour finishes are often softer than chrome plate; therefore a 3 year guarantee covers these finishes.
All plumbing installations must conform to the legal requirements laid down in the current Water Regulations.
