Answers:    Before using chemical cleaning , insert steel or copper wire around 1/8" (3 mm) diameter , bend its tip or end going on for 2" (50 mm) and twist this short length one or two times , push and verbs the twisted end thoughtful into the drain pipe several times , pull out and remove clogged fibers or strings , repeat until pipe cleaned , run hose down you may not require chemical cleaning . Good luck
You can use sulfuric acid drain cleaner from your local Lowe's or Home Depot, this is the strongest drain cleaner you can buy. Be highly careful using it as this will burn you. You will also want to depart from home for a hr or so once you use it. All you do is pour it down the stand pipe and let it do it's job-then run marine through the stand pipe and this will flush the remaining junk out.
