The drain was completely clogged by hair and soap
I’ve seen a lot of drains that are badly clogged and usually these types of problems come in commercial settings.
This week I went to help a residential customer that had a ton of soap residue and difficult water stuck inside of the drain pipes.
Overtime residue from soap and difficult water can accumulate and form a sticky substance that sticks to the inside of your pipes like plaque to your arteries. This sticky substance collects any hair, particles, and debris that is flushed or washed down the drain. When enough soap and scum plug the drain, the water flow is reduced and you end up with a clog and a backup. On Sunday I was helping a residential customer with a clogged pipe. I do not think that I have ever seen so much hair and soap scum in one place. The pipe was completely clogged and there was hardly any water going through at all. It took me 2 hours to wash all of the scum out of the fight. After that, I use a special component to check all of the pipes from the bathroom and the home office. There was sticky residue in almost every single one of the pipes leading out of the house, but by the time I was done unclogging every one of the drainage pipes, my afternoon was half over. The time went by so fast. After I finished with a bidet and toilet repair in the afternoon, I was ready to go home and put my feet up for the rest of the afternoon.
