We had a call from a customer who's boiler kept tripping the house electrics.
After some fault finding we found that the 2 port valve was leaking into the divertor valve head. We decided that it was best to replace both at the same time to save this from happening again. We drained, replaced, filled, bled and tested both valves.
Hot water and heating back on

🔥 Faulty Burner Seal – Don’t Ignore the Signs 🔥
This boiler was found with a failed burner seal, causing leakage and corrosion inside the unit. Left unchecked, this can lead to serious damage and potential safety risks.
⚠️ Issues like this aren’t always visible from the outside — they’re only picked up during a proper service.
✅ Annual boiler servicing is essential to:
• Keep your system safe
• Maintain efficiency
• Prevent costly breakdowns
• Extend the life of your boiler
Don’t wait until it’s too late — a simple yearly service can save you hundreds in repairs.
