Bicyclebill Posted February 12, 2018 Share Posted February 12, 2018 Wow, I’m embarrassed to say that today was the day that I learned that pvc glue doesn’t have to be blue. After skimping with application of the blue stuff to avoid poor aesthetics, I had leaks. Needless to say, my new plumbing project with clear cement looks very clean!

youcallmenny Posted February 12, 2018 Share Posted February 12, 2018 i'm ashamed to say I didn't realize this was an option either. Thanks for the tip Bill! Your new plumbing looks really clean. How long till you decide to get the fancy colored pvc from BRS? Quote Link to comment Share on other sites More sharing options...
Manny Tavan Posted February 12, 2018 Share Posted February 12, 2018 Same thing happened to me. First time around i used blue. Second time i used the clear pvc cement which makes a huge difference. Got mine from amazon “oaty medium clear pvc cement”. Didn’t use primer Quote Link to comment Share on other sites More sharing options...

jtarmitage Posted February 12, 2018 Share Posted February 12, 2018 Yeah, if you're using white off, clear is definitely the way to go for aesthetic purposes, though I strongly urge people to still use primer. You can get that in clear as well and makes for far better bonds. As we have a lot of vibration in our systems and tend to bang the pipes now and then working around our tanks, the primer creates a much stronger bond resulting in fewer leaks. I'd much rather do the plumbing right the first time than deal with the mess later...😲 1 Quote Link to comment Share on other sites More sharing options...

Zoolander Posted February 12, 2018 Share Posted February 12, 2018 I normally just use salt creep to stop all my leaks so this whole thread has been informative. 1 3 Quote Link to comment Share on other sites More sharing options...

I typically don't use primer simply for ease of application/assembly as I don't have to do as many steps and can be sure to get things together before they start to dry. Also, I would typically not deadhead any of my supply lines and hence am not applying much hydrostatic pressure in an aquarium application. Couple of thoughts come to mind with the article. One, which they mention, is that they did not test hydrostatic pressure. I could imagine a case could be made that the primer may help flow the "cement" and provide a better chance of a gap-free bond... which might not show up with the strength tests but could with a water penetration test. Also, such things as vibration or hammering could potentially reveal a practical difference. That said, the evidence presented argues for it not being a necessary step for most of the cements used. Interesting... Quote Link to comment Share on other sites More sharing options...

Gumby Posted February 13, 2018 Share Posted February 13, 2018 I used the blue just so I would forget what I glued. Clear can cover so mistakes of over gluing. Quote Link to comment Share on other sites More sharing options...
Bicyclebill Posted February 13, 2018 Author Share Posted February 13, 2018 Oatey now makes a combo primer/cement called Fusion and it’s clear. Costs twice as much, but I’m sure it offers a “synergistic effect” with a name like fusion. Sent from my iPhone using Tapatalk 2 1 Quote Link to comment Share on other sites More sharing options...

Interesting... Agreed! It would have been interesting to put water in those pipes and see when they first leaked.... Since that is more what we as reef people are after.. Still very interesting.

pdxmonkeyboy Posted February 23, 2018 Share Posted February 23, 2018 guys, guys ,guys, its not about making the plumbing look clean, its about wrecking your $160 jeans and carpeting. While I am sure a clear primer and glue combo could still wreck your clothing, you won't get the same DIY satisfaction that comes with going out to dinner with blue glue all over your hands.If they made a spill proof can of PVC... now that would be an improvement. Not that i have ever in my life spilled a whole can of pvc glue in my life. Sent from my SM-G930V using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
