Mixer symptoms
Four cases wesee often.
Each one of these points at a different part inside the mixer.
01
It drips after closing
If it keeps dripping with the handle fully closed, the ceramic discs inside the cartridge no longer meet cleanly. A single grain of grit is enough to score that face and keep the drip going.
02
The handle has gone stiff
A mixer that needs force to move has lost the grease inside it, or deposits have worked between the discs. Forcing it keeps breaking the cartridge, and you end up changing the mixer instead of a part.
03
The flow sprays sideways
When the flow breaks up and sprays to the sides, the small aerator at the tip is partly blocked. It is the easiest case of all, cleared by unscrewing the aerator and cleaning or replacing it.
04
Hot and cold are swapped
You open it towards cold and hot arrives, or the other way round. This follows a new installation with the two supplies reversed, or a cartridge refitted the wrong way up. The correction is simple and does not need a new mixer.
This area
What setsthis area apart
Maqwa is near oil fields, with villas and flats served by high-pressure tanks due to deep wells. Water here is very hard and minerals coat the cartridge faster than elsewhere. Mixers begin to cut flow or leak rusty water because of heavy mineral deposits. We inspect both the cartridge and pipe lines at once because deposits can block internal passages.
Maqwa is in Ahmadi governorate near KOC oil fields, an older residential area.
Water in Maqwa is noticeably hard, and heavy minerals block cartridges faster than in other areas.

The method
From the handleto the test.
Careful work on small parts, and all of it above the basin.
We close both angle valves
A mixer has two supplies, hot and cold, and both have to be closed. We then open the mixer to release the pressure still held in the two tails.
We lift the handle off
The handle is held by a small screw hidden under a plastic cap, and beneath it a ring clamps the cartridge. That comes off with the right tool so the mixer body is not scarred.
We change the cartridge
The old cartridge comes out and its seat is cleaned of deposits, because a new cartridge dropped onto a dirty seat gives you the same drip again before long.
We open it and check both
Both valves open, we run hot, cold and every position between, and we look under the basin while it runs to be sure the tails are not weeping.
Common questions
Questions about Mixer and faucet repair in Maqwa
The rust is from heavy minerals in the water, and old steel pipes are affected. We inspect the cartridge first and flush the tank if there is sediment, and water runs clear once we swap the cartridge.
Air is rare in Maqwa because pressure is constantly high. The noise usually comes from internal parts of the cartridge breaking, or water at high velocity hitting the seals. We inspect the cartridge and replace it if damaged.
