Copper pipes wrapped in duct tape under screed floor

Anonymous user 01/03/2024 - 3.03 PM

I have had a new radiator installed including moving of pipes. The plumber laid the copper pipes wrapped in duct tape (I could still see copper showing in some small areas) and the screed has been laid. I have been informed its been fitted 100% to Building Regs but I have concerns. My understanding Screed will cause corrosion on cooper pipes if not adequately protected but I'm told I'm wrong. I'd be really grateful for advice please. NOTE .... Thank you to you all for your responses, I really appreciate your help and advice to enable me to sort this matter out

He should have wrapped the copper pipes in denso tape not duct tape if they were in screed as copper does corrode if in contact with sand and cement

That's actually true. Screed shouldn't be touching copper pipe/joints itself. It can work together only if pipe is wrapped or sleeved.

Actual, if copper pipes buried under cement should be protected (sleeved), preventing the pipe from corrosion, copper exposed to cold weather or freezing temperatures outside or in lofts should be lagged.

I personally wrap denso tap around the copper then add pipe lagging as extra protection, over the years the mixture of products in the concrete will naturally corrode the copper piping which could lead to damages of the property due to pin holes forming in the copper. Every and any precaution to the copper pipe should be taken to limit future issues arising

That's very bad practice, the duct tape will degrade overtime and screed will corrode the pipes, also you will have expansion and contraction which will cause friction further damaging the pipes, best practise is to lay the pipes in conduit https://www.screwfix.com/p/jg-speedfit-15blk-con-25c-conduit-pipe-15mm-x-25m-black/72840?kpid=72840&cm_mmc=Google-_-Datafeed-_-Heating%20and%20Plumbing?kpid=KINASEKPID&cm_mmc=Google-_-TOKEN1-_-TOKEN2&gad_source=1&gclid=Cj0KCQiAyKurBhD5ARIsALamXaEB_-26i38x-5CafohEwxwMqkCB9xNcalKo-iV8lq8x5Cpx9jckMQQaAqisEALw_wcB&gclsrc=aw.ds
