I need to know what chemical will help dissolve calcium deposits from urinal pipes that are in the wall. Here's the story. I work at in a large industrial setting as a janitor and we have the "less famous" waterless urinals and we're finding when we change the "filters" that there is calcium build up causing the urinal to overflow. The pipes in the wall are pvc and there is no clean out pipes.
Any help will be greatly appreciated.

Thanks

What diameter are the pipes and is the calcium on the inside or out?

Toilet roll soaked in white vinegar dissolves almost any type of scale, it's legend, but you need to leave it to soak on the area to be cleaned.

Or you could try oven cleaner?!

The calcium is inside the pipe going out to the sewer pipes. I think we'd need something in a liquid form to pour down the drain after the waterless urinal filter is taken out. Any suggestions?

it is not calcium, it is urinary salt. we use muratic acid on regular urinals but i would seek advice from the manufacturer before i added chemicals to a mechanical drain. hate to see ya have to replace them because ya added stuff that hurt.
the fumes can hurt, use precaution.

the drain isn't mechanical. the waterless urinals are flushed with collect rain water. Is the muratic acid safe for the environment. I ask because I work at a environment safe factory.

I can not advise against using muratic acid, or any acid, in a enclosed area such as a rest room strongly enough. As a young boy I would take limed up toilet bowls out in the alley behind the shop and boil the lime out of them. Over half a century later my lungs still carry the scar tissue that the acid fumes caused. A few years ago I lost a good friend when he used a commercial drain cleaner containing sulfuric acid in a unvented bathroom. Acid IS NOT A GOOD IDEA to use to clear mineral buildup. Take it from one who's paid the price. Regards, Tom
