Overflow pipe - - > downpipe

Standard Toaster

Quick one.
I wanted to run my overflow pipe into the downpipe. When it does spill the water can be quite dark is is staining the kitchen sill.

Am I ok to do this or is it meant to be visable?
Eg to know when it's overflowing etc.

Seems to always drip when heating is on (oil fired, gravity fed)

Hiding it could mask some problems ok.
You could have a stuck ballcock and never know it.

I’d fear it would be more prone to freezing which isn’t good.

It shouldn’t be routinely overflowing, that in itself needs checking out.

It's should never over flow unless there is a problem. Find the cause of the problem rather than playing with the overflow

you have some issue with your heating system, perhaps as simple as the ballcock being too high up, with the tank nearly full, when heating system heats, water expands, pushing some out the o/flow.
When it cools down, tank refills...etc.

Note that this relates to the heating system header tank

Thanks for the replies all.
I don't recall ever seeing a f&e tank but will take another look and see. Thanks!
