Hi! to all,
Re: [SMW1] filter construction

I think I better clarify things here, especially for beginners.
1. PVC glue - use to join PVC pipe & fitting. Can also for male/female threads, thought no necessary. Within half a minute - it will dry & hold fast. So make very sure the parts are in correct alignment before fusing. Best to apply on both inside & outside for thorough fusion in order not to leak.
Tips here - if joint is small size = can use a Hair Blower to melt the glue in order to shift the position require or remove the joining.
2. Silicone glue - use this for PVC piping joining that you know one day you need to disconnect. Takes abt 8 hrs. to dry. Just hard one twist & will come out. Therefore, never use for piping under pressure, ie water pump outlet, Hi-blow air pump, etc.
Strange thing is - when use on glueing glass tank, 5 pcs. of glasses together - can take pressure very well! Even for 6ft glass tank.
Note - above 2 glues are never meant to patch up any FG tank cracks or any permantly bonding that need to take on heavy strength.. Must use fibre-glass repairing.
As I'd said earilier - after drilling the require size hole, fit in the male & female coupling with gasket on the tank inside & FG on both sides.
Or you may want to save cost & fit in a PVC pipe in directly & FG = then, *very important - the hole drilling must be just fit to slide in the pipe. Hold at 90 degree & FG. In my opinion - this method is risky. One hard knock can loosen the sealing & cost leak. Male & female joint can seal more firm.
For the inner side, will be female piece (larger surface) - you can cut off the access pipe leaving on the thread inner piece. this way, the compartment got more working space.
But then - if the drainage is on the bottom side , & one wants to drain off extremely low, then don't cut. Fit in a pipe & elbow piece to nearly touch the bottom.
For those that's is draining under the compartment (the most ideal) - no need elbow, just cut the piece to lowerest in order to get the max. drainage.
- if all these sound so blur & chim to you, , get a FG contractor & just pay the $$$...
Pray that he do to actually what you want. My bet is - not likely...
