ball valve change loft water tank

[hanban8]

Hi,


My overflow has been constantly going from the loft cold water tank. On looking the ball valve was very old and had been bent and tied and all sorts and it was leaking. I think it was a part one valve.

I have tried replacing it with a part 2 valve. I have it in place and tightened. My loft tank has a lip at the top and the white tap part of the valve is making the water spill over the side of the lip.

Is it possible that a part 2 valve won't fit my tank? or do i need to adjust it or get someone in to help?

Thanks any advice much appreciated (tried to attach a few pics)

Would it be possible, by using some appropriately sized washers, to space the valve further into the tank so that the white outlet could be swivelled away from the tank rim? If not, I fear that you will need to replace the valve with one that fits better.

I guess from your photos that you have a old water tank. Your water tank should have a tight lid along with many other requirements. Check this out http://www.wras.co.uk/PDF_Files/IGN9-04-04-Cisterns-Issue2.pdf. Hope it helps.

Weren't there two plastic nuts that moved along the thread and would allow u to move the valve body in closer? It's possibly / defo contravention of regs but just heat some hose pipe over end of spout and cut hose so it sits on the tank by 50mm but the end of the hose is at least 3" above water line. Tank looks a mess. Any rats or dead pigeons?

Beta float valves used to do one with a longer tail not sure who stocks them though......regards Turnpin

This is what you need its a longer tail and also the outlet is underneath and away from the lip of your tank, hope it helps,

As kris has pointed out you need a Part 1 to replace your old Part 1
