Frank Posted January 30, 2010 Share Posted January 30, 2010 I have a new tank that "looks" like it has a 1 in standard bulk head hole and a 3/4in standard bulk head hole. But....I have (2) Hayward 1in bulkhead which are larger than standard. DOH!Ugggh! What would be the best way to solve my issue? And...who wants to help fix the issue? My drill died and I need help!(icon) (fish)(fish)(fish)(fish)(fish)(fish)(fish)(fish)(fish)(fish)(fish)(fish) Quote Link to comment Share on other sites More sharing options...
grassi Posted January 30, 2010 Share Posted January 30, 2010 Is the tank glass or acrylic? Quote Link to comment Share on other sites More sharing options...

grassi Posted January 30, 2010 Share Posted January 30, 2010 Yes... new bh! Drilling the hole bigger is a pita. They suggest to cut and clue a little piece of acrylic (a "bridge") and then make a new hole on top of that. Didn't work for me :-( I had to make an acrylic disc and glue it inside the hole. Then redo the hole with the bigger bit. Quote Link to comment Share on other sites More sharing options...
grassi Posted January 30, 2010 Share Posted January 30, 2010 PS: I wish I could help, but I'm trying to finish the prop tank. I want it running by tomorrow evening ;-) Quote Link to comment Share on other sites More sharing options...
madmike Posted January 30, 2010 Share Posted January 30, 2010 dependent upon where the hole is located you could use a router and a template to route the hole slightly larger Mike Quote Link to comment Share on other sites More sharing options...
reef165 Posted January 30, 2010 Share Posted January 30, 2010 The problem is the pilot bit,and the hole saw wobbling when getting started.. I'm assuming the holes are inside a built in overflow. If you can put a piece of wood wedged inside the bottom of the overflow then drill from the bottom of the tank that will work. You just need to get the hole saw started, once you have got the hole's started with the wood in place, you can remove the wood and continue drilling the rest of the way through.

wegotjs Posted January 30, 2010 Share Posted January 30, 2010 Use a dremel , I was able to go up a whole size with just grinding it out. Works good and goes pretty fast. Quote Link to comment Share on other sites More sharing options...
steelhead77 Posted January 30, 2010 Share Posted January 30, 2010 Yeah, a Dremel or a Roto-Zip. You'll have bigger holes in about 5 minutes. Quote Link to comment Share on other sites More sharing options...
Frank Posted January 30, 2010 Author Share Posted January 30, 2010 Ok... got them to fit.. but here is the new question.. do you think a 1" drain and a 1" return will be enough?? I have always gone with 1 1/2 drain and a 1" return. Quote Link to comment Share on other sites More sharing options...
pledosophy Posted January 30, 2010 Share Posted January 30, 2010 Up all night Frank? I have a 1" drain on my 65g, it works O.K. Depending on how much flow you want from your return pump, bigger is better. 1" should handel about 600 gph. My return is a 3/4", which is fine for my needs. Just keep it the same size from teh pump to the bulkhead. Quote Link to comment Share on other sites More sharing options...
