Blocked drains are a common cause for concern that can easily be avoided. To prevent the congealing of substances blocking your kitchen sinks, make sure to separately dispose of oils, grits and greases. Even coffee ground, for example, if not appropriately discarded, can cause a potential block. If you’ve already tried a drain cleaner or plunger, make sure to shut off any water supply. The reason for this is to prevent overflow which could cause further damage. Make sure to contact a trusted plumber for a diagnosis and a speedy fix in Reservoir and speedy service in Eltham.
