This is the configuration of a typical sink P-trap / condensate tie-in. Every elbow decreases the flow of water, and promotes sludge build-up.
When this sludge accumulates in the P-Trap tie-in over the course of years, and we attempt to clear it with nitrogen, we can only blow a small portion loose.
You can see how the sludge restricts the sink drain. This reduces the flow of water, causing for slow draining and back ups.
The good news is, the problem can be fixed. By disassembling and cleaning the sink P-trap / condensate drain tie-in, your sink can be as good as new.
Firehouse Heating & Air does not perform this service, but we do recommend a company that does! JR & Son Plumbing will disassemble, clean and reassemble your sink P-Trap / condensate drain tie-in at a cost of $225 to $275. Call them today at (972) 285-4631.
