So I made a terrible mistake I finally started to glue/cement my plumbing and forgot to put the union nut in place. Is there any way to undo the glue/cement? It’s a union for my UV sterilizer. Also, is there anything that can help to clean the pipes as this project was a little messier than I thought it would be. Thanks!

you have to redo that part, you cannot un-glue. everyone has done it. only solution to mess is either light sanding. touchup paint/marker, or clean up goobers quickly

Well.. no there's nothing to remove the glue, you have to cut out and re-do it. Your best bet is to get a new union but if not you can drill out the fitting and reuse it. As you go you need to clean using pvc cleaner once it's set you won't get the mess off.

You can use a Heat Gun to remove it but it will destroy the pipe but save the union.

ETA: Ok after looking more closely at the photo I'm not sure a heat gun would work in your situation. It will work to remove a pipe but I think that fitting is too thick and too close to the union so the heat would also destroy the union I'm afraid....

It’s okay. I’ve already ordered all new parts. An $80 mistake

They make a tool to cut out the pipe from a fitting so you can reuse the fitting. The only time I have used one is to be able to reuse a fitting the was in a concrete slab.

As you go you need to clean using pvc cleaner once it's set you won't get the mess off.

PVC pipe cleaner also acts similar to solvent and softens the surface of the PVC prior to solvent application for a stronger bond. If you use PVC cleaner to clean any drips it will result in softening marks (White milky haze) all over your pipe. Best thing to do is wipe any excess off immediately with a disposable rag. Although once you do a few of these joints you should be able to get a hang of how much solvent to use so there is very little if any mess to clean up. :)

We've all been there, one of the many reasons I ALWAYS use a standard union after every specialty union on equipment and valves unless space absolutely will not allow for it, in that case I use threaded fittings. It's never super costly to redo a lasco/spears union, however it can be VERY costly replacing a union fitting on a valve or piece of equipment such as a pump, chiller or UV sterilizer.

I paid about $75 for the 3" model but that was much cheaper then busting concrete out. I know Menards has a cheaper line also.

Thanks for all the input! I’ve learned a lot. I was cleaning up asi was going, but that still left matte parts from the little dried glue. I thought about using less glue but I was so nervous about getting a leak
