Bulkhead

[Anonymous]

This is a 1" bulkhead that I am having a major problem finding fittings for at H.D. The oust side threads seem to have no fitting for it. A 1.5 female adapter is too big yet a 1.25 seems ever so small.

Is it possible I have a weird size here. If it wasn't a bulkhead and just a bolt I'd think I should be looking metric.

What gives?

Thanks!

Nothing will fit on the outside ya knucklehead. :lol:

Fittings go on the inside.

Thanks, Matt, but in another thread on another board I've already been told that I'm an idiot. :lol:

The outer diameter doesn't match anything close to a standard thread size. In addition, each bulkhead manufacturer makes the outer diameter differently (depending on how thick of a pvc they use). Whoever was able to fit something on the outside probably just lucked out.

Ok, so now that I can go to H.D. today and actually buy some PVC, is the theory to keep all my plumbing to 1" or up size it? For instance, on the 90 degree elbow that I'll by for the drain, will that be a bigger 1.5 ell?

Thanks!!!!

This is for the drain right? There is no benifit in expanding the pipe size. My HD advise is to by extra pcs. I can not tell you how many times I thought I had everything, and didn't. The wife jokes that any project I have to do requires 2 HD trips. 1 for what I need and another for what I forgot. I think she's right :?

That's what I figured since it will bottleneck anyway.

OK, so I bought some PVC today. I'm not really happy with how far the tank needs to be from the wall. Not really happy with the drain as well. Wish I could have both closer.

By the way, this is just a dry run with tape to hold the pieces together.

I've seen Tee's that are Slip x Slip x Male NPT. They're hard to find but it would save you at least 1-2" by removing that Slip x Male NPT fitting you have between the Tee and bulkhead.

Since this is a Durso standpipe, going to 1 1/4" piping for some distance (for example, down to the bottom of the tank or the first elbow) then reducing it to 1" might be a good idea. Reefland found that going from 1 1/4" to 1" made the durso siphon work better (I think it is easier to control the air).

2 things


1. I am knucklehead...


2. I agree with Len

If all else fails, change the bulkhead. They come in a variety of configurations (ie. slip X threaded, slip X slip or threaded X threaded) so it's possible to eliminate some of those fittings.

You should at least be able to find a slip X threaded bulkhead locally as they are really common. If that's what you end-up with, you won't need the adapter on the back (since you already have the slip X slip X slip tee) and you can use a threaded street 90 (see attached pic) on the intake (threaded) side of the bulkhead to eliminate the need for the other adapter fitting.

What Chris and Len said.

1.25" piping can handle more flow even with a 1" bulkhead. Especially if you rout out the inside of the bulkhead a bit. However, I doubt you will need it on a 40 gallon unless you are planning some major flow through your sump.
