I didn't have the time to read all 23 previous pages, but did anyone mention that if you have a yard and the tank is portable, like 75 gallons or less, you can take it out in the yard and use a trickling water hose to accomplish the same thing as the cup method? A lot less time and worry and you get a nice cleanup, all at the same time.....
Very good heat dissipation with running water........ ![]() |

I am worried that drilling holes in my tank will significantly weaken the strength of the tank. what do you think?

I am planning on drilling my 29g with a bit from lau. It shipped on the second and still waiting. Anyone know about how long it should take to get to Pa?

You should have it shortly. Mine shipped to Indy, took about 8 or 9 days. If I remember correctly. = )

What is the drill bit size for a 1.5" & 0.75" bulkhead? I need the size in mm & inches.
Thanks For those who think diamond drill bits are expensive, please look on ebay and buy the ones from HOng Kong ![]() |

|

that depends on if it's a schedule 40 or schedule 80 bulkhead.
what do you have? I used a 60mm bit for a schedule 40 1.5" bulkhead. |

I've been waiting for a 45 mm drill bit from Lau (Hong Kong) for over a month now, I've emailed twice and got positive responses, but I'm starting to wonder. This is holding up my project, as I need to get the sump finished.

Lau has very good service and every order I placed has been received. I would continue communicating with him. No order took more than two weeks to arrive, so I would think there is a problem in your case.

I agree, the service from Lau has always been top notch for me. I've ordered 3 times from him and no problems yet. I suspect that maybe he didn't have the bit you needed in stock and is waiting on a shipment of them? Maybe that's the case, just a thought.

hey all:
I'm ordering a 2" standard bulkhead fitting from Marine Depot. It calls for a 3" hole in back of my 46 gallon tank. I've already drilled two holes for two 1" bulkheads that are used for supply to my sump. The new bulkhead will be used for supply to a future Sequence Dart pump. It's intake is 2". Can I drill a hole for a 1.5" bulkhead and reduce the 2" intake to 1.5"? I've read that as long as you don't reduce the intake smaller than the discharge you're okay. But I've also read that the pump runs hotter and this may limit the life of the pump. Who's right, who's wrong? I just cant see drilling a 3" hole in the back of the tank. That's a pretty big hole. But then again a 2 3/8" hole for a 1.5" fitting is not that small either. Has anyone gone a differant route when plumbing their Sequence pumps? Thanks for the help. BTW: Awsome website. Cheers Ordy |

I drilled two 3 3/16" holes in each of my two tanks - one one each end to feed Sequence Dart pums. These were for schedule 80 bulkheads. I think you would be fine as long as you were at least 1/2 the hole diameter from any edge.

I have two 1.5" bulkheads that T together into a common 2" PVC to feed my Dart. That works well for me. |

Would 2 1" bulkheads be to small to feed a Dart with a 2" intake?

I have seen several mentions of diy bulkheads in this thread. Anyone have a link or summary of that arrangement?
|
#595
|
|||
|

I don't have the links for DIY bulkheads but if it was me, I wouldn't even think about using them unless it was in a scenario where it didn't matter if they leaked. I think they were using PVC fittings, one male threaded and one female threaded. The flange IMO just isn't big enough to assure me it'll be leakproof. Plus you have to find something to serve as a gasket. This of course, is just my opinion and not intended to slam anyone who uses them.
