How can I tell if my toilets and sinks are becoming blocked?
If you’re worried that your sinks or toilets aren’t draining effectively anymore, you should look at how quickly the water is draining off. If it is taking longer than it did before, a blockage may be forming in your pipes. Likewise, if water bubbles up out of other drains when you drain water off elsewhere in the property. If a smell is emanating from your drains, this is also a sign that your drains could be blocked.
