Drain dye

[Murph7355]

Before I order some, I don't suppose anyone has some old drain dye on their shelves that they want rid of? The stuff that you put down the drains so you can see where they flow to?

Happy to pay postage and even something to the cost if required - one of those things that I won't use more than once so don't want a load of it cluttering up the workshop or adding to the world's unused dye stocks

Alternatively, if anyone has highly amusing uses for it, let me know!

Could you just use a bottle of high concentrate rasberry/grapefruit squash? 99p for a litre of own brand and I figure must do the same job?

Possibly, though the colour of those things might make it harder against black/dark brown/silt laden pipes in shadow.

My understanding is that the dyes are much brighter.

Plain old water has covered some of the investigations, but it travels pretty slowly and is hard to tell which inputs are going where when it's already wet.

Orange squash from the 70s would have worked well

Bear in mind that a little drain dye goes a LONG way!

I'm quite keen to start slipping dye all over the place to see where it turns up/if I can do the village equivalent of what they do in Chicago on St Patrick's

Depends on which drain is being checked and where it discharges. It's a nugget that I gleaned off telly which surprised me (milk being a pollutant that is, not a nugget of poo).
