I'm about to install 2 Simer pumps for my v-drive sacs. The sacs have the standard two ports on the top. Can someone give me details on how they have attached their ballast hose to the sac ports without using the blue waterbed fittings? I don't care if it's permanent or semi-permanent, as long as it's leak-proof, non-restrictive, and doesn't use the blue waterbed fittings. As many details as you can.

When I was making my custom ballast, I went to the hardware store and found a pvc fitting that would screw right on to the fat sack. You would probably have to buy additional pvc or brass adaptors to make the tubing fit around and clamp it. I'm assumming you are using 3/4" ID tubing or higher. I ended up just going with the blue water bed fitting though.

I wish I was at home so I could take a picture and post it, but I'll attempt to describe instead. Take a short length of 3/4 inch ID hose and attach a hose barb fitting to the end of it. Shove the hose into the fatsac hole. It will be a tight fit so you will probably need some binding lube or soap to get the hose in. Shove it all the way in so that only the threaded part of the the hose barb thing is sticking out. Use a hose clamp around the outside of the fatsac port (the part where the blue waterbed would thread onto). Now you are done.

For the hose barb, you can either use the garden hose size threads or the pipe fitting size threads, depending on what you using in the rest of you system to connect to it. I used the garden hose variety and then attaching a brass garden hose quick connector to it, because I take my sacs in and out.

I used a long piece of hose inside the bag. I used about a three foot section of hose and cut a bunch of holes in it. This allows the hose to get way down in the bag and it helps for draining.

I replaced my hard tanks with 500 lb. bags and I just ran 2" (I believe,whatever the size of the hole is,,,) tubing straight into the holes and used a metal clamp to tighten..It's completely water tight, no leaks..Just make sure the empty/fill hose goes all the way to the bottom of the bag so it will empty all the way. Also, make sure your vent hose is in only a few inches or it will start overflowing before it's full...I had a post on here about it a long time ago..

Here is a link from a old post with some pictures of my sacks,(page down). No you don't need a bottom drain. The pumps will pull some air our.

airfreak's pictures are about the same as what I did. In fact, I think I remember reading that post back when I was building my system. But I like wilson's idea for a permanent install. Just shove the hose in there and clamp it on. No fancy gadets necessary.

The only reason I used the long hose with holes in it down in the sac is because I was having problems with the pump sucking the sac material up against the hose opening. That would block the water flow. So I made a hose with holes every 8 inches or so.

Thanks for all the good ideas!
