Hello guys I am redoing my bathroom and I hammered through the concrete and dug down to the 4” clay pipe cut it just behind the hub and I’ve used a 4” clay to 4” ABS Fernco fitting as seen in the pics I’ll post I can’t do a water hold test on these pipes so I filled a couple buckets with water and placed my garden hose in the shower drain and dumped the buckets down toilet drain , when I checked all the joints for leaks everything passed except at the side of the Fernco I joint that clamps on clay pipe , it’s very minimal leak but still leaks I left the water running down shower drain for 20 min and the leak dripped 2-3 times as seen in the one pic of the water that leaked out in 20 min , when I cut the clay I cut it as square as I could which turned out good , cleaned the pipe and pushed fitting on all the way and tightened clamp then I settled 4” abs and tightened clamp , I don’t have a inch pound torque wrench but I used 1/4” drive ratchet to tighten clamps and even after I found leak I tried to tighten more but am afraid to tighten it too much . Would this be a result of the clamp not tight enough ? Or is there a sealant I’m supposed to use on the clay pipe side ? The fitting is and will be burried under 2’ for gravel and 4” of concrete also will mention that the condition of the clay pipe is good , no cracks , gouges or pits in it so I’m not really sure if I did something wrong . From what I’ve read and been told , these are the connecting fittings for this type of connection and people swear they work and are good . Any insight , thoughts , fixes or solutions will be highly appreciated I have some knowledge of plumbing inside a house but this is my first time doing a burried connection and want it right , thank you and looking forward to speaking View attachment 135680

I think we should let @sparky handle this one.

The only thing I can think is check that the outside of the clay is close to perfectly smooth. Beyond that a sealant between the fernco and clay pipe would be my last resort. I personally wouldnt be worried about cracking the clay with just a nut driver.

Just flex seal around it then bury it right away. It’s what the pros do

 

[TerryTotoSucks]

Pour a bucket of dry hydraulic cement into the toilet and flush.

Repeat.

 

[jakewilcox]

Did you read the directions for the Fernco?

Because you clearly have an issue with that.

Make sure that you rub the fern leaves on all exterior surfaces of the pipe.

 

[jakewilcox]

Also, is clay pipe legal indoors in Canada?

Also, is clay pipe legal in doors in Canada?

Yes.

 

[Shadyear]

Why would you buy a fernco then not also buy the tool to properly install it?

Why would you buy a fernco? just push the 3” abs into the 4” clay, and stuff a plastic bag to fill the gap, it’s underground.

 

[jakewilcox]

Yes.

Well, I learned something today!

rock garden spray foam. they sell it ace next to the dikfers.

Like Terry suggested,get some dry hydraulic cement and flush a couple buckets down the toilet until the leak stops. It works similar to radiator stop leak but on bigger gaps.

We mix hydraulic cement with Rootx to ensure we get the ENTIRE gap sealed..............................

How did you tighten it up? Nut driver? Good luck.

This wonderful website for professional plumbers letting someone (the o.p.) register and he doesn't own a T-torquer?
I suggest banning Jimmyjames.

Ngl I just use an impact driver for ferncos and a nut driver for no hubs

 

[Lickitlikeafritter]

Should I lose my vetting because I don’t own a “t-torquer”?

i mean I definitely would use it if somebody here bought me a seekonk 60in/lb 5/16” torque wrench, but I am not plagued by leaks on no-hubs bands or ferncos. Even to the dreaded clay pipe.

 

[Tango]

On every job site in 20 years all you were handed was a 5/16 drill bit or you used your own 5/16 screw driver.

Same here, I’ve never had one and never needed one. They go from $70-$150 CDN, I wouldn’t be happy if I lost it.
