Ideal Boiler Logic Combi 30 Pressure Relief Valve PRV 176610

This ideal logic combi 30 pressure relief valve (PRV) 176610 releases excess pressure, so the boiler stays protected. However, if the seat wears or debris holds it open, it may leak and, as a result, pressure can keep dropping. Common signs include the discharge pipe dripping, frequent re-pressurising, and low-pressure lockouts. Therefore, replacing the correct PRV restores safe pressure control and helps prevent repeat shutdowns.

Frequently Asked Questions (FAQs)

1. What does the Ideal logic combi 30 pressure relief valve do?
It releases excess system pressure, so the boiler and pipework stay protected.

2. How do I know my Ideal pressure relief valve is faulty?
If the outside copper discharge pipe drips, or you keep topping up pressure, the PRV may be leaking.

3. Why is water coming from the PRV pipe outside?
It can happen if the PRV is stuck slightly open, or if the system has been over-pressurised.

4. What causes a PRV to leak?
Debris on the valve seat, wear over time, or repeated pressure spikes can stop it sealing properly.

5. Will replacing the PRV stop low-pressure fault codes?
Often yes, because it prevents ongoing water loss; however, you should also check for leaks elsewhere.
