I sounds like the cold side of the faucet has a bad side. Contact them for free parts for that side and directions on how to install. It could be just those rubber seals but my be the actuator for the cold water.

How to unistall franke mythos mtx taps

Turn off the water supply from the heater and at the main water supply line outside. place a container under the sink where the flick mixer is mounted to catch the water that will come out of the lines when you undo the fittings.
there should be 2 flexible braided lines coming from the mixer to the water supply lines, undo both fittings from those lines, then undo the brass nut that fastens the mixer to the sink, you may need a 10 or 12mm socket with an extension bar to get up under the sink to be able to undo the nut.
there should be a metal horseshoe shaped retaining plate that holds the mixer to the sink which should come off when the nut is undone.
You may or may not have to remove the flexible lines from the mixer which you should be able to sort out when you get to that point.
I hope this info helps you with your problem, the info may not be exactly how I have explained but that is how most mixers are fitted or removed.

Oliveri mixer taps

turn off the hot and cold water supply, place a container under the sink where the hose meets the Sink mixer.
release the pressure from the tap by opening the tap to let the water out.
use a suitable tool to undo the flexible hose from the underside of the tap, there should be a small "O" ring on it which you will have to replace as the "O" ring is possibly the cause of the leak.

I have a vitra minimax mixer tap needing a new cartridge. The problem is how to get into the mixer to change the cartridge - any advice on how to get into the tap much appreciated.

I've just done this. It is much the same as stated above. Isolate the water by turning the service valves below the sink 1/4 turn (Off). They look like flat-head screw heads or may have levers on (usually red & blue). Open the tap to check & drain the water in the tap. Below the tap handle there is a little round cap with the (red & blue) hot/cold indicator. This is plastic, so carefully prise it out (plug the sink first!). Now you can insert a 2.5mm Allen key in the hole and loosen a grub screw - you shouldn't need to remove it, just enough to release & remove the lever head. Next, unscrew the domed top. I used duct tape for extra grip as there was a bit of limescale. Now the Hex bolt is exposed. You need a 32mm spanner for this. Maybe grip the tap to avoid damaging it or the sink. Under the bolt is the cartridge. It should just pull out, but I had to struggle. Inspect & change your cartridge or washers - depending on what the problem is. My tap was held to the sink with a couple of bolts and had flexible hoses, so I took the opportunity to loosen the body, clean the limescale ring/dirt under the tap body and remount the it. You may as well clean / descale the other parts too. Now just reverse the above to put the tap back together. Open and close the tap to check for leaks. If there's still a problem, check the cartridge is properly seated and the washers are all good etc.

I have a mixer tap in the kitchen sink. The hot water tap runs fine but I am not getting any cold water. I also have a bath downstairs and the cold water tap there is fine

You will have to turn off your water mains and strip your mixer tap. It is possible that the seal (if it is an older tap with a rubber seal) has become stuck or the threaded part that turns it has gone faulty. If it is a modern tap with ceramic seals, check the operation of the mechanism and see why the ceramic seal is not being opened.

Can i drill a second hole for a second tap in a composite sink please

On all the composite lav. or kitchen counter top materials that I'm aware of you can drill holes as needed using hi-speed bi-metal hole saws.My advice is to just go slow to make sure you start straight and be extra careful when the hole saw is finishing hole to avoid rough edges. I hope this helps you. Thanks. It would be a good idea to wear a dust mask to avoid inhale dust.

I have mixer taps fitted to my kitchen sink which leak from under the mounting seal when the taps are turned on.when the taps are turned off the leak gradualy stops and the actual tap never leaks,do the...

It appears that the seal at the base of the tap is worn or the screw collar is loose - try hand-tightening it. It may cure your problem. Plumbers tape is a white tape that helps seal water pipe joints!

Leaking Kitchen Tap

I am assuming that your kitchen tap is leaking through the spout

if it is single lever you will need to remove the crown and spout by removing a small erasure size cap on the housing right under the spout or up near the back of the ever then use a hex wrench to remove the set screw( plug the drain holes do it does not go down the drain)

turn the water off (hot and cold ) under the sink
remove the set screw and lift off the lever

at his point you can take an adjustible wrench(channel lock and tighten the big ring nut that holds the cartridge in place

temorairly put the handle back on and put the handle in the off position turn the water on under the sink and see if it stopped leaking

if it still leaks you have to turn the water back off and remove the lock nut then the cartridge and go to big box store with old cartridge and name of mfg and get a new one and install

If you have seperate hot and cold valves on top of sink deermne which is leaking by turning one off with oher on undr the sink

once you have determined which it is (hot or cold)
take a phillips head screw driver( remove plastic clear cap on top of faucet handle with sharp crewdriver of knife blade) and remove the screw holdin the handle on to the stem(turn counter clock wise

be sure to turn water of under snk on both faucet risers after removing acrylic handle you then take an adjustible wrench and remove the crown nut turn counter clockwise until it comes off over stem

remove stem( looks like size of a pretzel about six inches long with washers on side and one on end

take the stem to local hardware(ace) or big box store and go to lumbing section ask clerk to inspect and recommend replacement washers or replacement stem (if needed)

go back reinstall and tighten crown nut snug( open (turn counter clockwise) tem valve before you snug it down with crown nut
install acrykic or chrome handle with brass phillips screw then ut cap on and turn on water and check for leaks

good luck

Bathroom sink ''mixer tap'' leaking internaly.

if your valve is single handle there is usually a small
button type of cover for (sometimes rubber the size of a pencil erasure) that covers acces to a hex key screw that you have to remove to remove the handle

once you have removed the handle you will need a large adjustable wrench to turn a large nut that holds the cartridege tighten if still leaks remove and replace you can math the assembly at HD or Lowes
