Water is a very valuable resource, nothing on our planet can survive without it so with this in mind it’s terrible to waste even a drop of it. This is even more prevalent if your home is on a metered water supply, you’re literally pouring money down the drain! As pretty much all taps feature a screw fitting that connects your connector of choice to the actual tap, this in itself is a form of compression fitting, but instead of using an olive, normally a rubber seal is used to create the seal once the connector is screwed up. As the seal is effectively not screwed down into its seat, this does in some ways reduce the wear and tear placed on both the seal and the seat so on the whole, they are a little more reliable than their rising spindle counterparts.
Compression washers, typically made from rubber or synthetic materials, work by compressing against the valve seat to create a watertight seal when the tap is turned off. Due to their simple, non-pressure seals they do tend to last a good long time, but when they do go, generally the whole cylinder mechanism and sometimes the whole tap need to be replaced. Before you start any plumbing work, turn off your water supply. Then run off any excess water through the pipes. Before you start to dismantle your tap you can put a plug into the sink so you don’t accidentally lose any small parts or screws. Richard told us, 'Not turning off your water isn't recommended. Most well plumbed taps will have an isolation valve on the water pipe, and this can easily be turned to the off position.With everything now connected up it’s time to turn the water on and make sure everything is working and there aren’t any leaks. He solved the problem by removing and then re-fixing the tap, ensuring that the tap and O-ring were aligned properly around the hole in the sink. One to watch out for – thanks, Lance! It’s important not to overtighten any washers or valves when you replace them, as this can cause excessive stress on the valve and will soon lead to dripping again. In older taps, when the tap is screwed closed, in the tap body a washer is pushed down on to a hole in the base of the tap that allows the water to flow and closes it off. Over time this washer will wear and allow a tiny amount of water to pass causing a leak. Compression taps are so-named because of the way the washer is compressed to form a watertight seal, as we described earlier. They’re the oldest and most economical type, while the modern washerless variations that you’ll also see nowadays are:
READ MORE...What Crucial Role Does Regular Drain Cleaning Play in Maintaining a Well-functioning Home? Changing a tap is a fairly straight forward job for both DIY novices and professional plumbers alike as long as you take your time and concentrate on the task in hand.Harry at My Plumber also advised that you should 'cover your sink with a towel, to prevent scratches.' 3. Unscrew the top of the tap Ceramic disc valve taps, such as modern monobloc mixer taps, reach maximum power after half a turn or less, and use ceramic discs instead of washers. Continually fixing leaks due to worn-out washers can add up over time. Replacing them proactively helps avoid unexpected expenses down the road. The monobloc tap is in some ways the best of both worlds; small and compact with all the benefits of a traditional mixer tap. Step 4 – Remove Tap Valve/Spindle: Using an adjustable spanner, set the jaws to the correct size, slip them on to the valve and undo it. Sometimes they can be very stiff and if this is the case use WD40 or similar penetrating fluid to loosen it
He replaced everything, eventually including the tap but any water splashed on to where the tap was seated resulted in drips underneath. Eventually he found that water was passing the ‘O’ ring supplied for the base of the tap. Rubber washers and gaskets are displaced and distorted more aggressively than some other materials under high compression forces. This can lead to increased signs of wear after extended use. Proper tools: A plumber will have all the tools required for this task, ensuring that your tap is fixed correctly without causing further damage. The valve seat is part of the tap where the spindle and washer press against to create a watertight seal. Over time, mineral deposits and corrosion can form on this surface, causing an imperfect seal which leads to drips.When the flow valve opens, the pressurised mains water that is held within the plumbing system passes through the tap spout. As the tap handle turns more, the rotating screw forces the washer further up and opens the flow valve more, allowing for control of the flow volume and speed. They’re very low friction in operation, further contributing to both longevity and a smoother, easier tap action - hence being used more often on lever-style taps Once cleaned, take your new tap and drop it through the tap hole. Pay attention to the seal on the underside of the tap that sits between it and the basin, bath or other. As you will probably notice from the images, the supply of water is controlled from a single lever (similar to the single lever mixer mentioned above), but as with all other taps, hot is to the far left and cold is to the far right, with a range of temperatures in between, depending on where the lever is positioned. Generally, more modern properties will utilize flexi pipes and push fit, whereas older properties tend to feature supply pipes that run all the way to the tap and compression fittings.
