I hope all is well.
I recently replaced my entire exhaust hose and water lock. Based on a few suggestions from the group I went with the Vetus Slang Hose. I was happy with the choice and installing that short section was not difficult.
I cut the hose to the old hose length, attached it to the water lock first, then to the unattached exhaust elbow, and then install the elbow in the original position with the hose already attached. This product is relatively flexible.
All the Best,
