Solvent Bonding PVC to Acrylic

[Platonic Solid]

I’m going to make a furnace condensate neutralizer out of a 4.5” O.D. clear acrylic tube filled with marble chips:
Base = PVC DWV Cleanout adaptor and flat screw-in plug
Body = Clear 1/8” thk Acrylic tube
Top = PVC DWV 4”-4”-2” Sanitary Tee

A PVC pipe will be stuck down the middle with the furnace condensate line dripping into it (not connected to it, just dripping into it). Thus the condensate enters the bottom – filters through the marble chips - drips out the 2” Tee into the condensate pump.

From what I can find online, Weld-On 16 appears to be a good product to solvent bond PVC to Acrylic. I looked at Lowes today, but they didn’t have it. I’ll stop by a few hardware stores to see what they say. Last resort will be ordering it from Amazon.

Any recommendations appreciated.

How about just using clear PVC tube and then use PVC solvent weld

Ive done hvac work for a lot of years,Ive never had any problems with water from a condensate drain affecting any plumbing.

rsanter: I'm only using acrylic cause I can get it from work for free. To purchase clear PVC, I'd have to special order way more than I need, thus I'd just go with solid pipe (which would remove the cool factor of seeing the marble chip status).

zmax: I think I could bottle the condensate from my propane furnace and use it as a rust remover (I should try that). It only took 8 months for it to eat completely through a 1/2" Type L copper pipe which was downstream from a 1ft 2" PVC tube filled with marble chips. From what I've read since, high efficiency propane furnaces put out the most acidic condensate.

I don't see a problem with it.

Weve got a lot of 90 plus furnaces around here,I have yet to see one of those filters in 20 plus years of 90 plus furnaces around here anyway.

Same here , in the last 25 yrs of these installs . Have never seen one or been told I need one .

In an attempt to justify my actions I took my water test strips and measured the PH. Unfortunately the label scale goes from light orange 6.2 thru red 8.4.
The test strip was bright yellow, so it's something much less than 6.2, which means I proved it is acidic, just not an exact number. As far as I'm concerned, the fact that it ate through a copper pipe in 8 months is justification enough.

How about just running it in pvc then?

I was waiting for you to say that. Everything is PVC or ABS now because of it. What I don't know is how the old dry well, that this drains to, is constructed.

So you worried that your old dry well might be constructed from copper?

LOL no. I've read too many stories online about acidic furnace condensate eating through cement.
It's not like this is an expensive project. Worst case scenario I'll have an interesting looking contraption that reduces acidity that I didn't really need. Even if it's just a placebo effect, I'm good with that. Kind of like installing a sonic pest repellant (and No, I don't own one).

I have one in our chicken coop. The squirrels were coming in and eating all the chicken food. Now they don't.

For a few bucks a epoxy for plastic should work. And maybe the pvc abs transition glue for plumbing might be another. Since you can get plenty of acrylic you can experiment.
