1. Turn off water and flush cistern

2. Remove old water inlet pipe and cistern inlet valve.

HANDY HINT: Place a bucket under inlet valve as an amount of water will

remain in the cistern.

3. Remove back nut from bottom of the new inlet valve, remove cistern lid and in-

sert valve ensuring stepped washer remains in place. Do not assemble backnut

at this stage.

4. To set correct height adjust inlet valve by rotating telescopic height adjustment

mechanism ( anti - clockwise for greater height and clockwise for less height).

The correct height is when the critical level mark (CL) is a minimum of 30mm

above the overflow tube. See pic below.

5. Fit back nut and tighten ( DO not overtighten).

6. Fit new BOSTON water connector.

(do not cross thread and do not use thread seal tape)

7. To complete installation it is important to clear debris from the

water supply. Turn off water supply.

7(a) Remove upper cap assembly by rotating anti-clockwise & pressing down

under slightly on cap.

7(b). Place container over valve top to minimise splashing.

Gently turn on water supply & flush for approx 5 seconds.

7(c). Turn off water & replace cap by rotating clockwise and locking firmly in

place.

BOTTOM & SIDE INLET VALVE

Need help?

Do you have a question about the FIX-A-TAP FIX-A-LOO and is the answer not in the manual?

The FIX-A-LOO® Bottom & Side Inlet Valve is a versatile plumbing component designed to regulate water flow into a toilet cistern. It is suitable for both bottom and side inlet configurations, offering flexibility for various toilet setups.

Function Description:

The primary function of this inlet valve is to automatically fill the toilet cistern with water after each flush and to stop the flow once the desired water level is reached. This is achieved through a telescopic height adjustment mechanism and a float system. The valve ensures efficient and controlled water replenishment, contributing to the proper operation of the toilet.

Important Technical Specifications:

Inlet Type: Compatible with both bottom and side inlet cisterns.
Height Adjustment: Features a telescopic height adjustment mechanism.
- Rotating anti-clockwise increases height.
- Rotating clockwise decreases height.
Critical Level (CL) Mark: The critical level mark must be a minimum of 30mm above the overflow tube to prevent backflow contamination.
Water Level Setting: The water level float should be set approximately 30mm below the top overflow tube.
Flush Volume: Designed for a correct full flush of 6 litres. Older toilet pans might require a larger flush volume.
Water Pressure: For areas with excessive water pressure (above 1000 Kpa), a pressure reduction valve on the main water line is recommended.
Connections: Utilizes a back nut for securing the valve and requires a BOSTON water connector for the water supply. Thread seal tape should not be used on the BOSTON connector.

Usage Features:

Installation Flexibility: Can be installed as either a bottom inlet or a side inlet valve, catering to different cistern designs. The installation process involves removing the old valve, inserting the new one with a stepped washer, and securing it with a back nut.
Adjustable Height: The telescopic design allows for precise adjustment of the valve's height within the cistern. This is crucial for ensuring the critical level mark is correctly positioned relative to the overflow tube, preventing potential water contamination.
Water Level Control: The float mechanism enables fine-tuning of the water level inside the cistern. Users can adjust the float to achieve the optimal water level, typically 30mm below the top overflow tube, for efficient flushing.
Easy Commissioning: The installation process includes a critical step for clearing debris from the water supply. This involves temporarily removing the upper cap assembly, placing a container over the valve, and briefly turning on the water supply to flush out any particles before reassembling. This ensures clean operation and prevents blockages.
Leak Prevention: The instructions emphasize not overtightening the back nut and specifically state not to use thread seal tape on the BOSTON water connector, indicating a design that relies on proper seating and seals rather than tape for leak-free connections.
Pressure Management: The recommendation to install a pressure reduction valve for high-pressure environments highlights a feature that helps protect the valve and the plumbing system from excessive force, potentially extending the lifespan of the device.

Maintenance Features:

Debris Clearing: A key maintenance step during installation is to clear debris from the water supply. This involves:
1. Turning off the water supply.
2. Removing the upper cap assembly by rotating anti-clockwise and pressing down slightly.
3. Placing a container over the valve top to minimize splashing.
4. Gently turning on the water supply for approximately 5 seconds to flush out debris.
5. Turning off the water supply.
6. Replacing the cap by rotating clockwise and locking it firmly in place. This procedure helps prevent blockages and ensures the valve operates smoothly from the start.
Leak Checks: After installation, it is essential to turn on the water and check for any leaks. This proactive check helps identify and address any sealing issues promptly.
Water Level Adjustment: The ability to micro-adjust the height of the water level float post-installation allows for ongoing optimization of the cistern's fill level, which can be considered a maintenance feature to ensure efficient water usage and proper flush performance over time.
Height Re-check: The instruction to re-check the inlet valve height to ensure the 30mm gap between the CL mark and the top overflow tube serves as a critical maintenance check to maintain hygiene standards and prevent backflow.

The FIX-A-LOO® Bottom & Side Inlet Valve is designed for straightforward installation and reliable performance, with clear instructions for setting up and maintaining optimal operation within a toilet cistern.
