REPLACING A SINGLE LEVER SINK MIXER
If you have a sink mixer that leaks or a mixer handle that no longer works like before, it might be time to get replacement. A professional plumber can make the job look easy, but this is not a DIY project, we need to follow the steps below to replace your single lever sink mixer.
DISASSEMBLING YOUR OLD SINGLE LEVER SINK MIXER
First of all we need to turn off the water supply to the sink or turn on the tap and let all the remaining water drain out. Place a towel over the drain so no parts fall into it or damage the sink.
We need to disconnect the Sink mixer tap from the water supply. It is handy to have all of the contents of the cupboard removed prior to the plumber arriving, this will save the plumber time and any extra cost. First turn off the mini taps, which should be under the sink for the hot and cold water supply to the sink mixer this can be done by turning the taps handles clockwise we will need to but a towel and a bowl under the taps to collect any water after this is done turn the n the single lever mixer tap on and move the lever between hot and cold this will relieve any pressure in the tap and to see that the mini taps have turned off correctly ( if there are no mini taps fitted or the existing taps are in poor condition or there is a chance they may leak we will need to install two new mini taps) this can be done by unscrewing the taps from inside the cupboard. first of all we will need to turn the water supply off at the meter which is usually located at the front of the property or in the case of a home unit to the left or right side of the kitchen cupboards or under the laundry tub once this is done we can remove the single lever mixer tap.
INSTALLING THE NEW SINK MIXER
If you have a new tap with a spray hose Slip the new sprayer hose down through the sprayer hole, and move it up through the center tap hole. With an adjustable wrench, link the hose to the sprayer nipple. The hot and cold supply tubes on the faucet may differ in length, depending on the brand, attach flexible connectors to adapt the tap for a specific installation.
With two wrenches, tighten each connection. Use one to hold the tap in place and one to turn and tighten the fitting on the flexible connector. This two-wrench technique will helps avoid kinking and damaging the tap’s copper supply connection. Insert and push the connectors and supply lines into the center hole, and, making sure that the tap’s gasket lines up precisely, seat the sink mixer.
Afterwards, under the sink, install a washer and nut to the end bolts that will hold the faucet in position. Hand-tighten the nuts, then tighten again using a basin wrench or box spanner. Attach the second flexible connector, and attach the other ends of the connectors to the shutoff valves. Tighten the connections using an adjustable wrench. Turn the water on at the shutoff valves, and turn on the tap to see if it’s working properly.
