Displaced rest bend?

[emeritus]

Hi, think this post is in wrong section... will move it

I had a blocked toilet which was jetwashed yesterday. The insurance contractor's cctv survey said the rest bend is displaced and needs replacing. I don't see a displaced rest bend in this image they sent?

Can anyone else please?

They want £350 to replace cast iron soil pipe in my conservatory that they drilled to access the drain. Previous owners had conservatory built over manhole so excavation of tiled sunroom would be needed to fix the restbend. I feel like I am being conned? Please help!

Hi,

Can anyone help please? Blocked upstairs toilet now jetwashed and working. Query re rest bend image.

My insurer used drain specialist Augur to cut cast iron soil pipe in my conservatory to access it for cctv drain survey to fix blocked upstairs toilet. They showed 1 photo in report saying rest bend is displaced, needs replacing, so does soil pipe and to do this my conservatory floor needs excavating and retiled for £350 (insurance excess)

I can't see any displacement?

No smell. Only 1 blockage in last 6 years since I have been here? previous owners built conservatory above manhole apparently hence access inside.

Thoughts greatly appreciated

I would presume they are talking about the step you can see between the pipe diameters, that would indicate that the rest bend could have moved sideways, i.e. displaced.

If it's a 110mm rest bend and the soil pipe is 4" or is it 6"(?) , if the former then the pipe ID's should practically line up, if anything the 110mm plastic would be slightly larger

Hi thanks for your reply. The report says replace 1 metre of 100mm pipe and rest bend. Do you see issues in the future with the pipe in the photo please?

 

[Madrab]

So is the cast Iron soil pipe the '100mm piece' needing replaced? So is the down pipe 4"?

Given there is, in effect, a visible step there, then it could be a place for debris/solids to gather, in the worst case then it could increase the risk of blockages. Whether it will cause a problem or not, then couldn't ever be sure but if there was an access created above it then it could be cleaned if there every was one.

Thanks again. So you do see a step, ok. I don't know the measurements of the pipes.. but if it ever happened in the future I can just get it rodded/jetwashed through the cast iron access they've put a bung in above. Seems like £350 is not needed to be spent right now - as long as no leakage into ground causing a serious issue later?

as long as no leakage into ground causing a serious issue later?

Cant attest to that I'm afraid as I don't have access to the camera images. Nor can we see the condition of the full bend.

@Hugh Jaleak may also be able to comment, no doubt having seen a few more of these too

If you get a measuring tape and measure the outside diameter of the cast iron that will tell you.

That says all you need to know... Classic upselling when insurance are paying, (most) of their no doubt rather large bill.

Looks to me like there's a Rubber Access point been fitted and possibly a section cut out the cast below, that has then been repaired with Denso tape. Whilst I would personally not be happy about having the repair internally, the rest bend is not 'displaced' it is merely a slightly smaller diameter that the cast.

Not sure how long you've been there, but if it's worked ok for a while, it may continue to work ok for a while more, replacing the rest bend may only move the reduction in diameter from the top of the bend to the bottom, and I know which end it would be better being at! Other, (possible and possibly cheaper), option would be to insert a 'Patch' into that section, which, (if done properly), would provide a more seamless run, and seal up any possible leaks between cast and clay bend.

I'd perhaps look to making a better job of the 'Denso' repair, (assuming that's what it is), if aesthetics aren't too important, get a Flexseal coupling, slit in lengthways, wrap it around the pipe with the slit at the back, and tighten the Jubilee Clips, this will provide a stronger, less likely to leak solution.

If appearances are important, then you'll have no option but to change the pipework sadly.

Thank you so much for your advice. I have been here 6 years and am going to leave it alone. The toilet flushes now and if it needs jetwashing again in another 6 years then I have an access point from the cast iron pipe above. I never liked the red paint on the cast iron soil pipe! I must say I don't like the black tape used to cover the pinholes originally made when investigating so thank you for the specific advice there.
