My cold water tank overflow is being used, causing a nasty patch of ice where it lands on the driveway. The cold water tank has never overflowed before.
Symptoms are:
* Cistern seems to take a long time to shut off.
* Ballcock was lying below the surface of the water. I had to pull it to the surface.
* There is evidence of overflow onto the plywood platform holding the water tank. Tea towels placed on the platform yestreday are now wet. Some slight spillage onto loft floor. The tank does not have a cover, I'm using a bit of board at the moment.
Recent work I've done:
* On Tuesday night, I had 2 pipe bursts in the loft, both on the cold water pipe feeding the cistern. On one of the repairs, I included an isolating valve with small plastic lever. This was because the existing stopcock was totally seized up.
Possible causes:
* Could the isolating valve that I fitted have altered flow to the cistern ballcock valve in some way?
* Is it simply a case of ice on the ballcock, or in the ballcock valve?
* Because of the burst pipes, I have had the central heating on full blast, with the loft door open. Maybe this is causing (excessive) condensation on the (plastic) tank?
I can post photos tomorrow. But access to the tank is very tricky.
