Tenants refilling the boiler in a shared house
The property
A post-war semi let to five students, with narrow heating pipes laid in the concrete ground floor to each radiator.
The problem
The tenants were refilling the boiler every couple of days, despite a leak sealer an earlier plumber had added. The landlord, living elsewhere, heard about it last.
How we found it
Closing the upstairs radiators made no difference, so the loss was downstairs. With the heating hot, thermal imaging found warmth at the foot of the stairs; a pressure test on that branch confirmed it.
The outcome
A tenant let us in and the landlord paid ahead, so the report followed straight after. The floor repair was priced on its own and carried out before we left.
