Every time we try flushing our toilet, it just swirls around the bowl and ever so slowly goes down. Does it do this on every other flush? No. Well, that ruled out an after-fill tube having slipped off of the overflow tube and, sure enough, once on site with tank lid removed, the ballcock’s after-fill tube was securely inside the overflow tube.
Root intrusion in sewer systems causes blockages, slow drainage, unpleasant odors, and overflow. Preventative root control is essential to maintain the sewer system's hydraulic capacity. This issue deserves our full attention.
