Answer: AQUQ-518115-HAN is the handle that fits Aqualisa 518113 Midas thermostatic cartridge.

Question: Does the Aqualisa 518113 need to be replaced if the water flow of the shower is extremely weak?
Answer: This will depend on why the Midas 200/300 shower is exhibiting such a problem.

– It could be an airlock. You can open all the showers and taps inside the home to release the airlock. See if this can bring water flow back to normal.

– Clear out the Aqualisa Midas inlet filter assemblies if clogs are present.

– It is possible that the clog is in the thermostatic cartridge. If this is the case, replacing the Aqualisa 518113 Midas thermostatic cartridge is the best and lasting solution.

Question: What is the difference between a high pressure and a low pressure Aqualisa Midas thermostatic cartridge?

On the other hand, a low pressure cartridge (AQUALISA-518114) goes with low-pressure, gravity-fed systems.
