Just tried it, first time on a tube and it kept going under ( submarine ing ). What am I doing wrong. Also there are holes on the bottom but no plug

Sounds like putting too much weight on the forward part. Had similar issue with mine but only when I slowed down, causing weight of the riders to shift forward.

Prob not enough air and/ or weight on front of tube- make sure weight is toward back so it can plane after that they can put more weight on front if desired.

I used the tube several times over the last few weeks. Didn't notice any holes on the bottom. However it did go under a few times. The problem was when the kids would lean forward in the tube. If they layed back we were fine. There has to be weight in the back. At least that has been my experience so far. We absolutely love this tube. Good luck.

We experienced the "submarineing" to begin with. To solve that the riders need to keep their weight back until you can pick up speed. Once you are up and running at a decent speed it doesn't dive anymore. We had the same problem on other pull tubes in the past. I'm not sure about the holes you mentioned. Hope this helps. Eric

Make sure your tow rope is long enough. I've never noticed holes on the bottom. If it is holding air in the tube and inserts, I wouldn't worry about it.

It sounds like your tube maybe under inflated, and we had to use a good air compressor to properly inflate the our tube. I have never had a problem with is submarining even with three teenagers laying on it and we used ours a lot over the last couple of summers. Like the rest of those that have responded; we have no holes in the bottom of our tube so I would recommend that you contact the manufacturer to see if you have a defective tube.

Does the amp work and power your subs? Trace your wires and make sure everything is in the right place. Do not turn the knob to full on yet cause it can't break easy, put it halfway or under half. And turn your car over and see if it works? If not send me another question and ill look at mine specifically

Did you insert it into the white hole/valve thing? maybe you need to insert it just a bit further. Otherwise sounds like you did everything right. Maybe your pump is bad, try another. Good luck!

I had two very similar problems and unfortunately, no matter how tight I wrapped the pipe, it didn't work. I used JB Weld, (not the water one-that didn't work), and it worked on one and still holds. I had to replace the copper pipe on the other.

ok. put the tube into the antenna until it seems to be fitting into some whole. then it should start to work.

same here got mine from CL. not a bad sub if you lay it on its side and plug the port (don't care for ported down fireing subs seal it and lay it on its side sna it will sound better!)

I had same problem. I found that moving the plug slightly up, down or left, right, it would start working momentarily. The connector is probably not fastened well to the circuit board. I returned mine and bought a different type. (thanks Amazon). This one works great and sounds better.

Thanks all for your help and advice. I called 3M and he said I should return it to the store. Sounded like the urethane had hardened in the tube. Returned this afternoon. Got a new tube with a current lot number. Haven't opened it yet. Here's hoping.

I have tried three different brands, really frustrated. I wound up just feeding in those tubs and getting new ones for water. sorry not to be of more help. I siliconed around plugs, tried plumbers tape too but neither held

Where under bottom? I assume you used Teflon tape/and-or pipe sealant. It its leaking through the switch in any way, discard the switch, its gone at that point..........

I've never done that but I'm considering drilling a hole in it. Mine seems to be doing the same thing. The first one I had didn't do that.

Mike, had this issue once with my old pump, I accidentally switched the L1 and L2 wires. Mark them first ( for the future) and swap them. I also heard to make sure the internal ground and the external copper ground is attached as well. Hope this helps, once you dial in the timers this pump is pretty awesome.

I purchased an inexpensive pump that you plug in. Otherwise.....you will probably pass out trying to blow it up yourself!

Mine does the same thing. I haven't bothered with it yet cause I haven't needed to hold it down. Best solution is to puts some tape around the plug on the part that goes into the hole and then glue it in with a quality glue. Before I glue mine I was also thinking about putting a solid 1/4" or smaller iron rod through the whole length off the inside to add some weight to it. You can purchase that at Lowe's and they should cut it to size for you. Hope that helps you friend!

Unscrew the top that is in the tube now, then replace with long needle tube it came with. You will put the plugger in the bottom like a syringe and push solution out of needle tube - like a shot, so to speak.

we had same issue - you have to pull the white 'plug' out and use a pin and pump like for a volleyball ... it was too bad that after we finally figured it out we found a hole in it and now its in a pile on the floor ...

Either ship it back or get smaller depth subs. I sent mine back for same reason
