Hopefully someone will be able to solve this little problem for me as I can't imagine what's causing it. Yesterday, I dislodged a chunky, foot long icicle from the overflow pipe of the cold water tank. Ice had also formed to about 6 inches inside the pipe. I cleared all the ice out and, for the rest of the day, there was a slow, continuous drip of water from the pipe onto the pavement below. This morning, following another cold night, the icicle had reformed as big as yesterday, almost blocking off the pipe entirely. After removing the ice, I went up to the loft to check the tank (there's only the one since the heating is all electric) and it was fine – water level just below the overflow.
There was an icicle in the same place a few weeks ago but I gave it no thought as it was just a one night cold snap. I'm pretty sure that, in the intervening period, there's been no dripping from the overflow pipe as I'd have surely noticed it. If the tank isn't overflowing, can anyone suggest a reason for the icicle formation (including the ice inside the pipe) during this cold weather? The water forming the icicle must originate somewhere...
Supplementary question 1: there's a pipe attached to the lid of my tank. What is this for and where does the pipe go (I couldn't follow it as I lost the trail under the loft insulation...)?
Supplementary question 2: While I had the lid of the tank off, I had Mrs pooksahib flush the WC and run the bath's cold tap. This was so I could (hopefully) watch the tank emptying and refilling properly. But there was no activity at all despite the bath tap running for at least a minute. I was expecting the main inlet to open immediately. Does this indicate a problem or does it maybe take quite a bit of water usage before the tank refills?
Many thanks to anyone who assists me.
