floatvalve leak - where to disconnect

Postby alanatdrm » Tue Mar 20, 2007 8:55 am

Hi, just woke up this morning to find water all over the bathroom floor, water dripping down into the kitchen and the overflow from the toilet cistern running like a river. I believe the float valve is at fault, as there was water spraying out.

I have turned off the water, but i'm unsure about where to disconnect the float valve as I have never done this before. My Colins DIY manual says that it must be unscrewed where it enters the side of the cistern, but on my one, it enters through a plastic pipe at the cistern base.
Could someone have a look at the photo, and hopefully suggest how to go about this.

Also, I believe new float valves come in three different types. High, medium and low pressure. From what the Colins manual suggests, I reckon I will need the Low pressure variety, as my cold water tank is in the loft, just above the bathroom. Could you confirm this?

Many thanks,

Simply Build It

where the pipe feeds into the bottom of the cistern on the toilet, there will be a nut visible - undo this. above this, there should be a plastic nut holding the float valve into position. if you undo this, you should be able to just lift the float valve out of the cistern. fitting a new one is the revers procedure, just remeber to fit all rubber and plastic washers back in place - new ones - when re-fitting the new float valve. MAKE SURE THE WATER IS OFF BEFORE OU UNDO THE NUT OR YOU WILL GET WET!!!! Any more probs just post them on here and i will keep an eye out for you. good luck
