Hello again, thanks as always to those who want to solve a question. I need to build a storage attached to the cabin. I have ordered a storage from baseco. There will be a hydrofor and water filter in the storage. Therefore, I need to run pipes through the storage floor. Are there any plumbing rings or similar that I should look for in the right diameter? How would you best solve such a task? I am attaching a picture.
I also consider asking: should I dig away some of the gravel and put some insulation around the pipes? It will be pier foundation, where there will be a 10 cm air gap under the storage. Maybe it will freeze there.
Thanks in advance for your answers! Best regards, Morten
