Do I glue all hard piping????

[kielty]

Putting together piping for 35 gallon refugium and sump...wondering if I glue joints or just fit them dry?

 

[ccoral]

glue everything well if not asking for problems

You fit them up dry, but for final use you glue anything that won't be submerged at the very least, most submerged things should be glued as well unless you are SURE they won't pull/blow apart.

Thanks,
I thought that was the way to go but wanted to make sure...
I'm assuming I don't need a specific types of abs cemant just the
standard stuff at the plumbing store?

The standard stuff is fine. The only thing that I did not "glue" is the durso pipe in my overflow. I want to be able to pull it apart and clean it. Since this is submerged and nothing flows up the pipe I feel this is safe.

Also, anything you think you may want to take apart later could use threaded connections instead of cement.

If you are talking about pvc, use a primer and pvc cement. But as mentioned above, fit it dry first and put it in place just to check and see how it looks. Think about how you design it and take into consideration any other equipment you may eventually want to have down there...

Best wishes,

This is a question I had as well. What type of cement should we use on the PVC? Also, does the tubing have to be hard pvc? I'd feel more comfortable with some of the soft tubing I've seen so I can work on the sump without disconnecting everything. Does the soft tubing cause noise/micro-bubbles or something?

 

[hmello@bermexin]

The only problems with soft tubing that I can see are

Collection points inside the tubing for detritus to collect in the folds if not completely smooth.

If clear or opaque could be good place for algae to grow.

And easy movement by other pets\kids making for possible trouble.

I have seen several setups where soft tubing is used as a "bridge" between the hard plumbing and the end points. This makes it easier to remove.

I've used soft in the past to make it easier to attach and detach things (more play) but I'll be going flex PVC this time. You have to watch the soft stuff--it can crease if you bend it too much and connectors will restrict more flow than PVC would because of the size difference..flex tubing connects INSIDE, PVC connects OUTSIDE. Plus PVC is a WHOLE lot easier to connect stuff..just unfortunetely a whole lot more permanent if you mess up.

And definetely prime and glue PVC. If you don't..even if it appears to not leak..you will most likely get slow salt creep through the cracks over the years.....I know I did and I glued them..just didn't do a very good job I guess (didn't prime either).

I thought about this, but in a long power outage do you think the whole overflow would drain?

if you have a typical canycane shaped standpipe with a vent hole at the top, the siphon will break and only the water in the overflow down the vent holes will drain. this is how mine works anyways. so its about 1/3 of the overflow.

No not because of the siphon, because he didn't glue his fittings. Would there be a noticeable leak?
I guess it would be rather small and the sump could hold the extra water.

Completely off topic.
Fizz...that's one handsome dude.
