    Is this glue safe to use for my plumbing in my setup?

    It looks like I can use it?

    Tangit All Pressure Glue 125g Tube - Detailed item view - AC_Aquatics

    and some more info :

    Tangit PVC-U - Henkel

    I cannot get my hands on any other pvc glue in Hermanus.

    Then the other thing :

    I want to replace the pipe that dumps the water back into the sump - connected to the overflow pipe, but I cannot glue it on and wait 12 hours for pvc glue to dry, to switch my return pump back on, so the question is : can I glue the pipe to the overflow pipe with superglue ? hope I explained it properly. ?

    On all pipes with gravity feed, I use silicone to glue the pipes together. And as long as its not under pressure it can be used immediately.

    Pipes that runs from a pump I rather use PVC weld.

    With the silicone together pipes I can always change the plumbing, as I've done plenty of times.
    Just check that you do not slightly pull one joint apart while doing the next.

    Itsunami been a couple of days since I've glue everything together,but there is still a strong glue smell.

    I have the pipes that i want to remove glued with silicon. But this is a separate pipe i would like to glue and i shouldn't have the need to remove. I'll try take a pic and post. Thanks for the input

    Thanx mate

    Tangit is the bomb. It pelts pvc together. Be sure to sand the 2 surfaces to be bonded to remove the shiny layer on the fitting and on the outer of the pipe to be inserted into the fitting.

    put a healthy application inside the fitting and use the nozzle of the 100ml tube of tangit to spread it around making sure the entire inner of the fitting has glue on its surface. Now the pipe to be inserted... apply a layer on the exterior of the pipe. Push the pipe into the fitting rotating it untill the tangit forms a seam.

    Be generous with the glue once off. Otherwise you may have a leaky fitting.

    Tangit bonds almost instantaneously so all the above from when the fitting has been sanded should be completed withing 10-20 seconds.

    I have put the system back online after a few minutes of gluing a joint.

    I prefer to tangit all my fittings personally. Im not a fan of silicone but this is a personal preference.

    Thank you @Fraser W . I cannot get my hands on PVC weld. Tang it is the only PVC glue i can get.


    Thanks Leslie, This is very helpful and appreciate your input.

    I glued the fittings together this morning and damn, that stuff is strong. I didnt sand it though. Hope it doesnt leak, if it does, ill have to buy new fittings and do it again. I have noticed a strong smell of glue inside the glued fittings after a few hours. Is this normal? Should I be worried?

    No stress about the glue smell. It will dissipate in time. The fittings may have bonded lightly due to you not sanding. Just keep an eye on them. If enough glue was applied the bond should last a very long time but for 100% peace of mind sanding is advised.

    I have an old 210lt deep freeze full of old fittings. I bought a heat gun and am able to rehabilitate fittings for emergency purposes.
