This video demonstrates how to replace the washer/diaphragm in a Torbeck toilet fill valve. The process involves isolating the water supply, removing the old diaphragm, installing a new one, and then reassembling the valve. The presenter concludes that while replacing the entire valve might be simpler, this repair method is effective and cost-efficient, especially in difficult-to-access installations.

Isolate Water Supply

• 00:01:35 Before servicing the valve, the water supply must be isolated. This can be done using an isolation valve on the toilet's water pipe or by turning off the main water supply for the property. Once the water supply is off, the water stops exiting the fill valve, allowing safe access for repairs.

Remove Old Diaphragm

• 00:02:34 After removing the nut and arm of the valve, the diaphragm is exposed and can be removed. The old diaphragm is likely perished and covered in black residue, indicating a need for replacement. It is important to note the location of the tiny hole in the diaphragm, as it will be needed during reassembly.

Install New Diaphragm

• 00:03:40 The replacement diaphragm, typically found in a repair kit, needs to be inserted correctly. The tiny hole in the diaphragm must be aligned with a pin on the valve, ensuring the correct orientation. After insertion, use the flush mechanism to lower the water level and prepare for reassembly.

Reassemble Valve

• 00:04:05 The float arm must be correctly positioned and aligned with the plastic lug on the valve's inlet. The green nut securing the float arm should be tightened with care, ensuring the valve is held securely to prevent damage. Once tightened, the water supply can be restored, completing the repair.

Torbeck Valve Assessment

• 00:05:00 The presenter expresses a preference for valves with more brass components over plastic. Although the repair is successful, the presenter suggests that if a new valve was required, one with brass components would be a preferable choice. This emphasizes the presenter's opinion on product durability and material quality.
