Drain line stoppage in Tampa. Drain line stoppage in Tampa. This galvanized waste arm (what the kitchen drains into) had no minor clog. Drain line clogs such as these are many times due to years of build-up from grease, hair, and other foreign debris. Rather than using a plunger or chemical drain product, which are meant for small amounts of drain blockage, this drain line stoppage needs a plumber who can pinpoint the highest concentration of blockage and repair the drain line. Some tips for preventing a clogged drain line are: not pouring grease down the drain, using a plunger rather than a chemical product (like drano) for minor clogs, and using strainers or drain covers (especially if you are a restaurant owner!) while rinsing dishes at home or scrubbing floors at a restaurant.
