Frequently Asked Questions (FAQs)

1. What is a Baxi 3-way valve without bypass?
The Baxi 3-Way Valve Assembly Without Bypass Kit 7224764 controls the flow of hot water between the heating system and domestic taps. This valve assembly replaces part number 5132456 and ensures smooth switching between heating and hot water demand.

2. Can you change a 3 port valve without draining the system?
You don’t need to drain the tank, as when you are draining the heating system, also the coil inside the tank will drain itself. In order to replace the 3 port valve you only need to drain the heating circuit

3. How to check if a diverter valve is working?
A diverter valve may be faulty if your water is lukewarm, if your hot water taps work but your central heating does not or if your hot water taps only work when the central heating is on.

4. Can a diverter valve cause low water pressure?
A worn pump that’s losing efficiency, a partially blocked heat exchanger, or a faulty diverter valve on a combi boiler can all cause reduced hot water pressure even when cold water pressure is fine.

5. How does a diverter valve work on a combi boiler?
A diverter valve can be found in nearly all combi boilers and provides a fundamental mechanical function – it essentially controls the flow of your hot water. It allows you to control where your hot water is sent on-demand i.e. to your shower or taps.
