Time for some updates! It took a while to permanently glue my plumbing. It proves to be quite a challenge.
Good thing Monday is a holiday here in HK (Mooncake Festival) so I had quite a long vacation plus my leave last Friday.
It was a good decision to take a day-off from work, as plumbing is not that easy to do. At least for me who’s doing this the first time and the dummy in me did not know that the PVC glue would actually melt the plastic and let that pipe slip all the way to the stopper. Good thing I tested it first with my durso pipe otherwise I was already contemplating on sanding the pipes and reducer for the manifold. Sometimes the Chinese label in the glue does not help to remind you that this is a solvent.
Ok! I made some grinding on the pipe ends to smoothen the flow of water and increase its velocity.I think this is the priciple of the the so called “Port and Polish thing in the intake manifold when you do some engine modification. I made used of Dremel same tool in widening the BH holes. This is done by thinning out the edges till it is level with the T stopper. This way nothing will impede the flow of water. I have no idea on what implication would be in the turbulence which we are supposed to create but this seem to be a good idea for velocity increased.
I did cut and fit everytime, to make sure that when I glue them together it is a perfect fit. Make sure you plan the sequence when gluing them together. Do a practice run. You could no longer recover when you insert the manifold with a glue and the one I’m using dries fast. The paranoid in me place silicone in all possible water leaking points on joints. I have space limitation as you could see, a leak that will come up later when frag are stablished would be disastrous.
