They are a solid sleeve and our people think they're quite an improvement over ferncos.

Is there a reason you can't use a coupling like Romac or Smith-Blair?Tue, 13 Nov 2007 17:34:21 GMT01687289http://www.wef.org/TechnicalDiscussions/Topic2774-11-1.aspxWe use a shielded coupling from Mission Rubber that we like a lot better than Fernco. It does cost a little more than a Fernco shielded coupling.Fri, 21 Sep 2007 12:52:32 GMTMHhttp://www.wef.org/TechnicalDiscussions/Topic2774-11-1.aspxIf you have a lot of leakage problems AND need some additional capacity, you could try replacement of the VCP with C-900 or C-905 PVC. This is fairly easily done by pipe-bursting and fusible pipe (no joints.) If you are interested, I found help at this web site for the PVC: <A href="http://www.undergroundsolutions.com">www.undergroundsolutions.com</A>Wed, 24 Jan 2007 13:20:56 GMTD Shulmisterhttp://www.wef.org/TechnicalDiscussions/Topic2774-11-1.aspxIn my experience, transitions to/from VCP are difficult.<BR>The pipe's outside diameter (OD) is different from that of PVC, DIP, CIP, even from mfr to mfr.<BR>I've seen the steel banded flexible-type couplings used, but supplemented by concrete encasement of the joint.<BR>There are other brands of couplings out there too, some with much more substantial steel banding.<BR>I'll post the names if I can dig them out of old files.Wed, 24 Jan 2007 10:10:40 GMTCSi_Guyhttp://www.wef.org/TechnicalDiscussions/Topic2774-11-1.aspxI would like to know what problems you have encountered with fernco connectors.Sun, 15 Oct 2006 15:15:27 GMTJohn Pampaloni Jr.http://www.wef.org/TechnicalDiscussions/Topic2774-11-1.aspxOur City is in the process of SSES and systemwide repairs. A recurring problem has been the previous use of Fernco type adapters for VCP repairs and transitions. We are looking for a hard coupling system to use for these repairs. Are there any suggestions? Vendors and manufactureres have been no help so far.Wed, 13 Sep 2006 09:19:31 GMTwwjcveng
