I need to know how to glue SDR 35 (the blue water pipes the city uses) to
black ABS. Will regular ABS to PVC transition glue work? or do you need a
special glue for glue the blue SDR 35 pipe?
Thanks in advance,
I may have been off-base here. Sched 35 is normally for sewer work
(Green). Heavier wall pipe is used for municipal water supply.
In any event, check that the ABS you plan to use is specifically
marked "for potable water use" and that the fitting dimensions match.
Call the utility and ask if solvent welded (glued) joints are
permitted between the two materials.
Some people have asked me what exactly I am trying to do. Here an
I am joining an ABS adaptor on a Backwater valve that allows you to use 8"
SDR 35 pipe instead of the standard 16" access sleeve that comes with the 4"
Back water valve. The back water valve I have is made by Canplas. The
access sleeve that comes with the valve is only 16 " in length. Canplas
makes an adaptor that will allow you to use 8" SRD 35 PVC pipe instead and
then cut it to the length you need. The adaptor also comes with a lid that
fits the 8" SDR 35 pipe.
If some one is looking for the part from Canplas it is a 23304 -4" ABS
Sleeve Kit. This is the work around if your sewer line is lower than 16
inches . Mine is about 19". Hope this explains what I am doing.
Thanks for the advice,
Check the fit of the pieces to be joined. If it's a reasonably
tight fit, go ahead and use the multi-purpose solvent/glue.
If not a good fit, go to the Fernco site I posted and select a
coupling. Using a Fernco coupling has another advantage if
you are cutting the backwater valve into an existing line in
that you can just drop the valve in place and then slide
the couplings over the joint.
