Ideal Pressure Relief Valve Kit PRV Boiler Safety Replacement Part

Ideal Pressure Relief Valve Kit 175413 protects your boiler by releasing excess system pressure. If water drips from the discharge pipe or pressure drops frequently, the PRV may have failed. A stuck valve can cause constant discharge even when pressure looks normal. Replacing this kit restores stable pressure and reliable heating performance. Supplied with a 12-month warranty.

Frequently Asked Questions (FAQs)

1. What is Ideal Pressure Relief Valve Kit 175413?
A replacement boiler safety valve (PRV) kit that releases excess pressure to help protect the boiler and heating system.

2. What does a PRV do in a boiler?
It opens automatically if system pressure gets too high, venting water safely through the discharge pipe to prevent damage.

3. What are common signs the PRV needs replacing?
Water dripping from the external copper discharge pipe, repeated pressure drops, or needing to top up often via the filling loop.

4. Can a PRV cause the boiler to lose pressure?
Yes. If it’s sticking open or the seat is worn, it can continuously let water out and the system pressure will keep falling.

5. How do I confirm compatibility before ordering?
Match part number 175413 and check your boiler model details against the compatibility list in the above listing description.
