There are two ways that filtered water may be supplied. Firstly via a separate worktop mounted tap, or a combination mixer tap which has hot, cold, and filtered water. The later is often more convenient as no additional space is required on the worktop and many people prefer the convenience of a single tap. Initially You should check that your water pressure meets the minimum / maximum pressures required by the manufacturer. Bromley Plumbers are experts in all plumbing work.All in One Water Tap.Made up of a new triple outlet tap, flexible pipe tails, mounting bracket for the tap, filter unit and mounting bracket, and flexible water hoses to supply the filtered water. There may also be additional items such as a filter changing indicator.Mounting the Filter Unit.They can often be mounted in the horizontal plane instead of the vertical plane which makes it easier to find the best position under the sink in the kitchen.Connecting the Plumbing & Mounting the Tap.If you are not confident, call a Bromley Plumber to carry out the job. Isolate the hot and cold water supply to the sink. Drain down the pipe work, and fit suitable double check service valves before proceeding. If this is a new installation, or the position is unsuitable, you will have to modify the pipe work to suit. Disconnect the existing mixer tap hot and cold flexible tails from the supply pipes and remove the tap from the sink or worktop. Place the upper mounting gasket on the base of the tap assembly and position in the tap hole. Secure in its position using the horseshoe shaped plate and stud together with the mounting washers. If fitting to the worktop rather than the sink unit, hopefully the tap hole in the worktop will be the same size as that required for the new tap. If not, or if this is a new installation, you will need to cut the appropriate size hole in the worktop. Connect the flexible pipes to the hot and cold water feed. Connect the hoses to and from the unit. Re-open the isolation valves and inspect the job. Open the filtered water tap and allow to run for a minute or so to flush it through. Repeat for the hot and cold taps.

A tap which fails to supply water when it is opened is said to possibly contain what is known as an airlock. This will cause the water to stop flowing in the pipework. Bromley Plumbers undertake all manner of plumbing work.Removing the air lock.To remove the lock you can use a hosepipe and attach it to the tap that has the airlock and the other end to a working tap. In most cases this will be the cold tap on the kitchen sink. Open both taps and let the pressure of the mains water force the air back out of the pipes. Leave it for some time, then turn off the air locked tap. It could take a few goes like this to release the lock and allow water to run freely. When done, undo the hose from the higher of the two taps, before releasing the lower one and allowing the water in the hose to drain away into the sink.Air lock at more than one tap.When more than just one tap seems to have an airlock, then clear it from the lowest one. It may also be possible to blow out the airlock if the above method fails to work. Place a hose into the outlet pipe of the loft tank. Open the tap at the other end and then blow through the pipe to try and dislodge the lock.Draining down to remove an air lock.As a final resort method, drain the system down. A Bromley Plumber has the right tools to drain down. Turn off the water feed and open all the taps to drain the water. Close all taps until they are about a three quarters closed. Turn the water supply back on. Adjust them all until a light, even flow of water is achieved. Now go round opening them one by one to the half-open position, starting with the lowest and working upwards. Repeat at the three quarters open position. Once all air has been discharged, turn all taps off to a point where there is only a minimal flow. Finally, close them all before checking the operation of each in turn.

Modern WC systems can be too small to house a traditional ball float syphon flush mechanism. Therefore the inlet valve is either a modified diaphragm type wit a very short float arm, and miniature float, or an ingenious vertical valve with a float cup that fits round the central column of the valve body. Bromley Plumbers have expert knowledge on this subject. Both are very quiet when they operate however the float cup will be slow to fill the cistern if it is fed from a storage tank rather than mains supply. In these slimmer more modern systems the old syphon flushing method is replaced by a plastic valve operated flush mechanism that is operated by button fitted in the cistern lid. This also incorporates an over flow. The button is in two parts, depressing one part for a short low volume flush and both together for a full volume flush. The button is linked to the plunger rather than the older style wire link float arm system. Installing.The valve design is very ingenious but can be very tricky to make adjustment for a correct fit so when installing the valve must be adjusted so that the critical level on the body of the valve is at least 25mm above the top of the overflow pipe. There is a threaded shank at the base of the valve assembly which gives the relevant adjustment so that correct positioning can be achieved. Guaranteed installation work for this equipment can be carried out by a Bromley Plumber.The float cup inlet valve consists of a rubber ring seal at the base of the cistern which will probably need to be replaced in time but with spares available should not cause too much trouble. It is a good idea to keep any instuctions and drawings regarding the unit should you need to replace a defective seal at some point.
