Hi all.
Went to a breakdown a few weeks ago. Potterton Promax, 4 months old, water dripping very slowly from bottom of outer case. Took case off, air box door off, no obvious signs of a leak. Checked flow switch first, dry as a bone. No wet patches on outside of combustion chamber, or inside beneath flow/return trappings. No water stains around manifold. checked flow/return pipes above boiler, nothing. And no wet patches in the sump so unlikely to be hex either. Yet a tear drop of water would gather at the corner of combustion chamber about every two minutes. Came to assumption its likely rain running down the plume kit and back along the air intake into boiler.
Has anyone had a similar problem? How was it resolved?
Thanks.
