Hello
We had our 831 installed about 18 months ago never had a problem with it until now. Saturday morning came down stairs to water dripping out the bottom of the boiler. The system pressure was stable at 1.2 bar so I took off the front cover and the inside was awash with water - cleaned this up but couldn't see any leaks - checked around the system and found a puddle of water on the top of the boiler. So called out BG - the BG tech couldn't find any leaks and did not know why there was water on the top either he did find a loose cap on the pump which he done up tight as he thought that might have caused it. It happened again on Monday morning with water dripping out of the boiler had another look inside but again no visible leaks - there had been very heavy rain with strong winds over the weekend so when the BG tech arrived to have another look I mentioned this and he now thinks this could be rainwater coming in through the outside flu and would also explain the water on the top of the boiler.
The outside flu is angled up slightly but the BG tech says this is normal as to stop the acidic condensate from running out of the flu.
Can I chip some of the mortar away from the flu so as to angle it down some to stop the water from getting in or would this stop the correct operation of the boiler? Also does the cap on the pump need to be done up tight as it wasn't before and had never had a issue?
Thanks for any advice
