Leaking Monobloc Mixer Tap

[pioneer1963]

Good Evening, I've recently fitted a new monobloc mixer tap to the wash basin in the bathroom however when i turn the tap on water slowly leaks from the top of the tap. I've tried reducing the water flow to the tap but it doesnt seem to make any difference. Any idea if this can be rectified, thanks

Being a new tap then you contact the supplier for replacement.

I was hoping for a quick fix, the basin needs to come off the wall to change the tap and it's very awkward due to its position. I was wondering if I took the red/blue cap off and unscrewed the holding screw whether i could do something then

 

[Alanc]

Where is it leaking from ?
do u have a picture ?
if u take it apart and make it worse, if it's new then contact supplier and tell them that u should be compensated for replacing.

If on the other hand these are cheap taps from the bay....then find leak and seal lol.

is it the type with a screw in the back holding the spout on?

undo the screw and remove the spout, check the o rings are in good condition and grease up (sillycone grease) and refit.... see if that helps.

Faulty blue cartridge, or slight chance the brass holding nut needs tightening.

I would go with awheating's view on this matter, he beat me to it lol

If you take the packing gland out, slowly turn the water on , this normally is a good tip to remove debris and has worked for me then silicon rubber parts and put everything back together

Thanks for all the replies, I will remove the screw and spout tomorrow and have a closer look at the o rings and take it from there, will let you know

 

[Koogatubac]

Most important will be the packing gland washer or the cartridge depending on what tap you got, good luck if you can post some pictures which helps ALOT more when you have a problem

I've taken a few photos of the tap assembly, the water is leaking up from the square in the centre, i've tried tightening the brass nut but it has not made any difference

 

[stevetheplumber]

if the large nut is tight then you need a new cartridge

 

[pioneer1963]

Thanks for that Steve, can you advise what the cartridge is and if its a part i can buy in a local diy store like B&Q

SEDAL 35mm Replacement Ceramic Disc Cartridge E-35 AZ SD Bath Basin Sink on eBay!

You need to know whether its 35mm or 40mm.

Thanks Phil, Can the cartridge be replaced with the tap in situ without disconnecting any of the flexi hoses from below as access is very, very limited and the basin needs to come off the wall if any attachments need to be disconnected

 

[Phil]

Turn water off and crack open the brass nut you'll need decent grips or adjustable and remove cartridge.

No need to mess underneath.

Thanks again Phil,can you tell me which part of the cartridge I am measuring to determine whether it is 35 or 40mm

 

[Phil]

Hi, useful thread thanks. Mine was a similar internal leak, on a BRAND NEW Kadya MT3006 basin mixer. This new one just had the large top-nut a bit loose, and was allowing water past the bottom seals (between the cartridge and the internal centre "floor" where the outlet ports line up with the bottom of the cartridge). The thin blue seals are only just proud of the cartridge base, so need to be pressed well down by that retaining nut (in this make anyway)!! The water can find its way out via the small locating holes for the base of the cartridge, and these holes are just "open" to the hollow tap body (hence water can leak from the bottom of the tap - hard to spot unless you have a small mirror and torch handy). Strangely enough, the new one is replacing a 3 year old one of the same make and model, with a very similar internal leak (but that one has an older design, with a slotted ring, rather than a 22mm HEX - and a special tool is needed to remove it). Thanks for the useful link too, very useful for spare cartridges.
