Return pump fit disaster

[Mariette]

I Hope because I would feel horrible not being able to help.

quick question and hope this does not add stress, you also need to think about the other side you are putting the hose to. The barb coming out of the pump will need to be same as the barb you are plugging hose into

There’s a solution in here somewhere. I know it. I just do. So don’t worry, I’m sure we can work something out

The internal diameter of the barb, the hose, and the “other barb” are the same. I checked.

One possibility (if I understand your question) is to heat up the hose with a heat gun or in boiling water (just the end) to make it more pliable and then when you slide it on to the barb and cinch it down with the hose clamp it will have a tight seal (this is only recommended if it is a reasonably close fit, otherwise look for an adapter or larger hose). Good luck!

That is exactly what I did

So I’m writing off the flex hose and going to try rigging something w the hard pipe it came w. Will need a small piece of plastic hose to connect the hard pipe to the pump barb. Just have to make sure the hard pipe fits around the ATO ... I’m calling it a night. It’s 945 pm here. Will update tomorrow.

Thank you all for all the help so far

Sometimes a break is best to do.

Take your time and do some more research before you lock in on hard plumbing the return. One concern is the potential vibration - many people that hard plumb still include at least a short piece of flex hose which would seem to put you right back to searching for adapters. Please know that we are cheering for you!

Yes please? Break time

It appears that’s exactly what I’m going to do. The hard plumbing doesn’t fit into the barb either. So I’m thinking I’ll attach the barb to the hard pipe using a hose. I dunno. I’ll rethink this tomorrow

It appears was though the pump is already equipped with a union. That would be the large nut that is in the picture. IF you have a union then I would heat the hose, put a skim of silicone on the barbed fitting and push it on. Barbed fittings have a way of leaking and silicone plain eliminates that problem. IF you don't have a union in the assembly then add one with the necessary reducer. You always want to be able to disconnect the pump. You might also consider adding a valve if disconnecting the union - at some future date - is going to release a lot of water.

What you need is one of these that will screw into your pump and replace the one you have. Make sure the male screw in part is the correct size. Use some teflon tape to seal the threads. You then cut the top off, down to the size that your hose fits on. Secure with a hose clamp.

Just to be clear, for the 3/4” barbed fitting that comes with the pump, you’re using 3/4” ID (inner diameter) tubing, right?

 

[WVNed]

1" Slip / 0.75" Slip
It says your pump uses slip fittings. You are probably trying to connect a piece of flex PVC with a fitting on the end.

Perhaps what you need is a piece of PVC pipe that goes into the 2 fittings to join them.

I think I’d be helpful if you took a picture of your pump and all the associated fittings laid out clearly. It’ll give us a better understanding of what you’re working with and how to properly help. At this point, we’re all kinda troubleshooting blind so to speak.

This. Please post a picture.

We need a pic with the fittings and pipe/hose OP is using. Too much guesswork without it.

I should mention that the tank came pre-drilled w pipes already permanently installed in the overflow box. As in siliconed in there. They then provide tubes that attach from the bottom of the tank and go to the sump. I can’t just put in a different tube. I’d ideally have it match the internal diameter of the tube in the return box and then I would have to seal it onto the fitting so I could attach it to the tank. Make sense?

In rereading some of the OP’s posts, it seems that the soft hose attached to the rigid return plumbing of the tank is not 3/4” ID hose. So we need to know what the ID is of the return hose supplied with the tank so we can find the appropriate reducing barb connector so we can use 3/4” ID tubing to the pump.

Perhaps something like this...

You may have got it, but I’ve used the heating the tube trick many times before with tubes that for all intents and purposes should not have fit over the barbed fitting they were intended for, including my own return pump.

Just takes a lot of manhandling, persistence, cursing, and growing irritation lol you’ll get there eventually, and that sucker should never come off!

 

[Water Dog]

I’ve used the end of the hose in boiling water trick many times... it works well!

 

[Mariette]

After reading everyone’s helpful comments, getting overwhelmed, cursing the plumbing gods, and considering smashing my tank to pieces, we have a solution.

Flex hose (came w tank) has been scrapped. Hard pipe (also came w tank) subbed in.
Pump is connected to a tube which is connected to hard pipe which is connected to the tank.

Thank you ALL for your assistance. Big special shout out to @Mastiffsrule for your dedication and help.

Check out my build thread for pics once it’s all plumbed. It’s titled “Tank made possible by R2R”. Should add “tank and plumbing...” hahaha

Thanks all
