Mineral buildups

Residue from different cleaning products and cosmetics builds up over time in the valve. Water leaks from the pipe and inner mechanism can also produce mineral buildups.

You can get rid of the residue buildups by using vinegar. You can use the vinegar inside and outside of the valve and the cartridge.

With a scrub brush, the deposits can loosened from outside and inside parts. Thus you can clean the buildups and use the valve the same as before.

Wrong cartridge

If you use the compression valve, you will face a hard turn valve more often. It is for the usage of the O-rings valve stem, which gradually becomes weak after frequent use.

Try to use the ceramic cartridge as the rubber seat makes the valve stem work smooth in any condition.


Sometimes the valve friction makes the usage hard. It is for exposure to heat and air through the nozzle. Excess exposure hardens the seats of the valve stem, which increases the friction. By this, the shower valve gets stiff, and water leakage starts to destroy the inner parts.

So to avoid such friction, use lithium or silicon-based grease in the valve. This keeps the valve turn smooth. Plumber grease will keep the rubber working for a long time.

Worn out seals

When you find the seals are completely worn out, there is no option but to replace the seal with a new one.

One thing you have to check is to take a similar seal to match the parts of the valve, or else it will not work.
