Twyford SF1151CP & SF1152CP Sola Thermostatic Cartridge - SF-51CP/​T

SUMMARY

The Twyford SF-51CP/T is a thermostatic shower cartridge for the Twyford Sola SF1151CP and SF1152CP thermostatic shower valves. It is the internal temperature control cartridge used to regulate the blended outlet temperature by reacting to changes in the incoming hot and cold water supplies.

This cartridge is used when the shower valve is no longer controlling temperature correctly, is difficult to calibrate, or requires cartridge-level servicing after the water supplies and inlet filters have been checked. Before ordering, compare the existing cartridge and confirm the valve model code where possible.

Pre-Order Check

- - Check the valve is a Twyford Sola SF1151CP or SF1152CP before ordering.

- - Isolate both hot and cold water supplies before removing the cartridge.

- - If the shower has flow or temperature issues, inspect the inlet filters, non-return valves and supply conditions before replacing the cartridge.

Troubleshooting

- - Symptom: shower runs too hot or too cold. Likely Cause: thermostatic cartridge not regulating correctly or supply temperatures outside range. Solution: confirm supply temperatures, clean filters and replace the cartridge if regulation does not recover.

- - Symptom: temperature fluctuates during use. Likely Cause: restricted inlet flow, pressure imbalance or worn thermostat assembly. Solution: check hot and cold supplies, clean inlet filters and service or replace the cartridge as required.

- - Symptom: cartridge is difficult to remove. Likely Cause: limescale or aged seals around the cartridge body. Solution: use the correct 30mm spanner and take care not to damage the valve body.
