Two of Mary’s garden soaker hoses failed their pre-installation checks with leaks from around their connectors. The problem seemed to be a break in the hose inside the connector, with water spewing out of the connector around the hose. Having previously fixed a gash in another hose, I figured I might have some success at fixing these leaks.
The general idea is to squish enough silicone rubber inside the connector to seal around the hose, then clamp the hose and connector snugly enough to hold the rubber in place:
The enlarged recess fits around the brass connector shell, which is squashed loosely around the hose and from which the leaking water emerges. Of course, because this is a different hose, the previous model didn’t quite fit and I had to doodle up new geometry:
As before, I bandsawed aluminum backing plates to ensure the plastic didn’t get all bendy in the middle:
The hose clamp (!) around the connector on the far right ensures a split in the brass shell doesn’t get any larger.
They’ll spend the rest of their lives under the garden mulch, where nobody will ever see those bulky lumps. Life is good!
