CWS tank overflowing from No 36 Homer Close, rented property, tenants seem unconcerned.
The overflow exits onto the communal path in front of my property and is used by many residents daily.
 No 36 is flat above mine and CWS tank is shared by us both, to alleviate the nuisance to others I am having to run off hot water twice a day which is just an unavoidable waste.
I assume you have landlord details on record and thought you may write to them to apply pressure to get the problem solved.
What was an occasional drip is now becoming a constant stream as the ball valve seal breaks down.
Approaches to the managing agents have yielded no results to date.

Thanks
