overflowing sistern with torbeck valves

The water level must be really high to do this. ;-)

I've never worked with the Torbeck. However, if it is anything like the Fluidmaster, it needs to be spotlessly clean. It is possible to dismantle them and scrub the mating surfaces. It then needs to have a blast with the cap off.

Of course, the Torbeck might be completely different.

For all the cost of a new valve it might be worth installing one and seeing if this makes a difference. I fitted a Torbeck valve to my 50 gallon loft cistern (the "cold tank" if that makes it clearer - the thought of needing 50 gallons to flush a toilet... sheesh! ;-) and after about 6 months (I think) it started giving me some problems. I probably posted the query here, but a quick email to the manufacturers and they sent me some replacement parts. Sounds like some design problem. Hasn't been any bother since.

Torbecks are sensitive to even tiny bits of crud. Unscrew the big ring and remove the washer (there a small pin it fits over). Make sure it's all clean - hard water areas make it worse. Put it back together and see if it's then OK. (there are tiny balance holes that can get blocked).

Tip: Unclip the float (note the position!) before trying to undo the ring. Less likelihood of the float rod getting broken if your hand slips...

The one in my downstairs bog makes a 'boing' as the water shuts off. The others (upstairs and in the loft tank) don't. I've cleaned, inspected etc. all to no avail. Any suggestions?

Fit a water hammer arrestor close to it.

I think Torbeck and Fluidmaster are both sensitive to dirt, and hard water. I replaced all mine with conventional ball-valves in the end. I did a search on Torbeck, and they can be troublesome.

Does it have the flow restrictor fitted?

The Torbeck I fitted in our bathroom was trouble free until I had to clean it earlier this year...in a hard water area. YMMV, as they say!

I unscrewed the valve again to clean it. It is a cylinder with a rubber washer and plastic cap at one end and rubber diaphragm, small plastic piece with a tiny hole in and a plastic pin at the other side. Finally there is s small cap at the diaphragm end which pushes in with a small locking tab and this cap has a tiny hole in it. All are spotlessly clean - it still leaks from the output pipe which comes off the top of the valve. The only thing I can see is that the small plastic piece with a hole in it - the hole does not look perfect and the small plastic pin seems very short and is falltened at the end that goes through the hole. The float has a small rubber piece in the arm that fits over the hole in the vale - this looks good too.

Wonder if I can get replacement parts for the inners of the valve - I think I bought it from screwfix.

How much is a full replacement from Screwfix? Under a tenner? Why not treat your cistern then.

Install several other toilets, so you can play tunes.
