OK, I think I owe Adam, Mike, Fax, and Dion a beer.

I ripped off all the silicone and teflon tape and glued the pvc. No bubbles.

It will not be coming out any time soon though. Thanks Guys.

Everything I have read about these externals says that having the pump suck on the input side will shorten the life of the pump (the bearings go out quicker). I don't know if you would run into the same issues that I have with microbubbles. It is really annoying though.

BTW, Great looking pair of tanks!

All this talk has me thinking about how I want to plumb my Iwaki 40 onthe new 90g (see other thread).  To conserve floor space I may want toplumb the pump over the sump on a small shelf.  I can bolt it down withstainless or nylon screws so it can't fall in and I have this sweetcheck valve that should keep it primed. 



I was thinking of putting the check valve in the return chamber with ascreen on it, up to a union  then to an elbow on the intake side.  Theoutput side would have a union followed by a ball valve to shut it offto clean the pump, then it would have a wye to go to each SCWD.

Anybody see any problems or concerns?

Thanks,

It is 1 inch pipe and it has a u-tube over the edge of my 20 high so there are 4 bends on the intake side. I have a valve on the output side of the pump. Does reducing the flow solve cavitation?]]> Mon, 09 Jul 2007 14:14:51 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=19023&PID=166849&title=plumbing-an-external-pump#166849 <![CDATA[Plumbing an external pump : How many bends are on the intake...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=19023&PID=166829&title=plumbing-an-external-pump#166829 Author: fj40fax

How many bends are on the intake side of the pump, and what sizepipe?  if it is too difficult to pull through it will causecavitation which will cause air bubbles too.]]> Mon, 09 Jul 2007 12:59:22 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=19023&PID=166829&title=plumbing-an-external-pump#166829
