How To Install An Under-Sink Water Filter

nstall a Water filterNow you know what a drinking water filter can offer, here’s an easy to use, step by step guide to getting it all fitted and fully functional in just a matter of hours:

1. First of all, turn of the hot and cold water supply – and you’re boiler if necessary. Make sure the area around the sink is clear and you have easy access to your instruction manual and the underside of the sink.

2. Next, install the tee (also known as a saddle valve) that comes with your chosen DIY kit by screwing it onto the appropriate drain pipe that leads up to the sink basin from the u-bend.

3. Now you have to ‘mount the water supply’ by fastening the plastic tubing that comes with kit to the supply valve. Make sure you cut down on any excess pipe (except for the black waste pipes – they come later) that might get in the way once this has been fitted.

4. Hang the plastic filter unit on the side of the cupboard under the sink at the specified height, and then attach the sink faucet and lines (including the waste line) to all the unit fittings underneath (this will mean unscrewing the faucets first). The waste line will help prevent clogging once the water supply has been turned back on.

5. Next, install the drain adapted under the sink too, fitting it directly onto the ordinary supply pipe.

6. Once that’s all done, you can cut back the waste lines that are now attached to the filter fittings as well – just make sure the remaining lines are aimed downhill and are free of any constricting loops that might prevent the flow of water after they’ve been pushed into the adapter directly below the sink basin.

7. Finally, screw the plastic unit into place and make sure it is fully secure before connecting the final water supply line. The water filter should now be fully functioning – just make sure you sterilize it and test the supply before using any water from the faucet!

Of course, if your DIY isn’t up to scratch and/or you don’t feel comfortable installing your water sofener, there are a number of picture diagrams online to help you with the process; if not, then you could always look around for a fully qualified plumber or contractor to do the job for you. They usually know all the parts by heart and –as longer as there are no surprises or hiccups – will have the whole thing finished in just a couple of hours.
