Default Corrosion

A customer sent me these pictures today, angle stops and supply lines are about four years old. I asked him if he keeps any chemicals under the sink and he said he keeps grout cleaner and bathroom cleaner under there. Do you guys think that could cause this?

Absolutely would cause that. The bathroom cleaner surely has bleach and I bet the grout cleaner does as well. Toilet bowl cleaner has HCl which will strip rust leaving behind perfectly clean steel ready to rust more. I see this a lot.




Stainless isn't stainless to everything. Each grade of stainless has its pros and cons. Even the best stainless can corrode. I think we can all agree those flex lines don't have the best stainless.




I would swap those for some chromed copper lines and then if he insists on keeping chemicals down there, open, that you spray the metal parts of the plumbing with some clear coat spray paint.

Yes, chemical cleaners with lids that don't fully close mix with other fumes in a confined space like a cabinet sink that has no ventilation. I think I made a thread about this.

Many people have floods because the braids corrode out and the plastic tubing inside bursts. I sometimes hand out an article to my customers and I tell all of them not to store cleaners and dain'os underneath. I also write on the bill they were told about it.


Plus some plumbing contractors got sued in my area because the braids busted not one but twice in 6 months if I remember correctly. The contractors had to prove they were innocent by sending them to engineers and labs. The culprit, oblivious customers who store chemicals.

I saw that but he didn’t mention any leaks. He may of tried to clean the corrosion before he texted for service.

I thought I remembered a thread about it. That’s why I texted him and asked about chemicals under the sink. I would guesstimate about 80% of the sinks I come across have chemicals underneath with no signs of corrosion.

Is that bathroom humid? I went to one that had that earlier this year. This was during early summer/ late spring. Their a/c didn't work very well up there on the 3rd floor so it was really humid. The angle stops and supply lines for the sinks and toilets were all like that. They didn't have any cleaning products under the sink or near the toilet.

It def looks like there is a leak on the tail piece, where it ties into the basin, see the drops, also the poly hose for the faucet, has a few drops of water on it. Leaks like this in a warm house can cause humidity esp in an enclosed space(vanity cabinet)..
The supply lines are rusted, the chrome esc. plates are rusted, the PO lever arm is rusted, I’d say more humid/wet conditions vs chemical corrosion... yet off gassing of some chemicals can cause this.. but it seems to be more wet/humidity conditions.

We can all agree it's not just a drop of humidity but a lot more!
