Innovative Plumbing Aid

Though I admire the innovation in plumbing I am going to describe now, I was no part of the thought process behind it or implementation of the same. I was a mere spectator.
The architectural consultant and contractor for repair and renovation of our hospital building was a wonderful pair. The former designed and the latter built on the designs. The drainage of the sink in the OT was one such wonder so produced. There were three outlets, and they were drained into a single pipe which to the main drainage. The drainage pipe was set at an angle of about 15 degrees with the horizontal, presumably to aid drainage by gravity. Unfortunately the same gravity pulled downward on the pipes and the joints, which in due course came off. By that time the wonderful due had bid us adieu. The hospital plumbers were apparently not equipped to deal with such a situation. Finally the servants of the operation theater tried different methods, as follows.

1. They put buckets under each leaking joint. That prevented spill on the ground. But they had to emptu the buckets frequently, which was quite a bother.
2. They got hospital plumbers to repair the joints. The joints would not stay repaired due to gravity as we saw before. In order to support the joints from below, the servants put empty plastic cans below them. That looked like figure A above.
3. The plastic cans were light and would get bent by pressure of the plumbing. So they replaced them with paver blocks, which the contractor's workers working elsewhere in the compound were glad to give them. The hospital plumbers fixed them with cement. The end result is as shown in figure B above.
