This made the steam inside it condense, creating a partial vacuum, and atmospheric pressure pushed water up the downpipe until the vessel was full.
The rainwater downpipe headers which collect from the roof gutters are each embossed with dates.
A small tube from another downpipe is sometimes used to keep the trap from drying out.
This is clearly a fault in design, and it seems to be a fairly common fault that the drains and downpipes cannot cope with rain water after a heavy downpour.
On any estate in my constituency one can see that putty is missing from windows, that there are broken downpipes and that there is often no lead flashing.
The same applies to cleaning of rones and downpipes.
After additional works were added including kerbs and re-routing of the downpipe, the final cost will be approximately £43,000.
I put my hand on the boarded area that obviously houses a metal downpipe and that was wringing wet.
