Urinal - over enthusiastic flush

Try fitting a 1/4 turn service valve to the offending side and turn it off slightly?

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember John saying something like:

Put a restrictor in the flush pipe.

radweld for car radiators stops hot water under pressure.

or chemical metal?

I had thought of that, but it is plated pipe and I don't really want to disturb it. However, it does sound like a good option.

Chemical metal sounds good - car repair shop?

Those two part leak sealing epoxy putties would do the trick - DIY sheds sell it in short strips of two colours where you tear off a bit and mix it until uniform in colour. Sticks like the proverbial to a blanket and sets hard.

If it uses compression fittings, a 'penny washer' between the pipe and fitting will be inconspicuous.

You may have to construct a 15mm 'penny washer', and shorten the pipe slightly to give room in the fitting for it.

Doesn't seem the right approach at all. If you do anything to the nozzle (for want of a better word) you will disrupt the pattern of flow over the porcelain. So you could end up not washing down some areas but still having an excess flow over others. And if you make that adjustment with something like epoxy putty it could be very difficult to remove/adjust in future (if it doesn't quite work).

I agree that you need to do something about the absolute flow from the cistern.
