Question: Why is the water temperature unstable when the shower is in use?
Answer: Water temperature that goes up and down with a steady water flow rate could mean that there is a problem with the 3/4” dual control thermostatic cartridge. Try replacing the part and see if it solves the issue.

Question: The shower’s water flow is unstable and so is the water temperature. Is this because of the thermostatic cartridge of the 3/4” dual control valve?
Answer: There is a variety of factors that can lead to inconsistencies in the rate of shower water flow. This affects the performance of the 3/4” dual control thermostatic shower valve cartridge.

– Blockage in the feeds or in the shower valve: Over years of use, grit and minerals can harden in the pipes and/or in the shower valve. It restricts water from freely flowing through, thus, the fluctuating water flow and temperature.

– Water pressure problems: Pressure is the force that pushes water in through the pipes and out from the shower head. The pressure between hot and cold supplies to the shower valve must be the same. If one is weaker than the other, the temperature can be abnormal.

Water pressure can change over a period of time. It can be best to periodically check it.

– A broken thermostatic cartridge: Since the 3/4” inch dual control thermostatic shower cartridge also controls water flow, this can be one of the signs the shower valve part is in its last legs.

Benefits of Applying Grease on the ¾” Dual Control Thermostatic Shower Valve Cartridge

Use silicone grease on all the seals of the replacement thermostatic cartridge for the 3/4” inch dual control shower valve prior to fitting it in the valve.

O-rings or seals are typically made of rubber. It keeps water from leaking out and it can wear out or harden after some time. Heat-resistant, silicone-based grease formulated especially for plumbing protects these rubber seals from abrasion and pressure. At the same time, it seats and seals the new cartridge in the valve precisely.
