The issue of our slow Scamp
sink drain revisited.
confirmed the diameter for the sink drain is .75" ID. So armed with that information I stopped in at Lowes when we went into town for groceries. They had many types and sizes of plastic hoses on rolls.
They had 2 types of ID .75", one was clear and the other with a "cross hatch" pattern with fibers to add strength. Both are very very stiff and hard, the type of tubing you would need to soak in very hot water to soften before slipping on to the connections.
I opted not to buy any at the moment. I did use the old remedy of a couple of TBS of baking soda in the drain followed by 1/4 c of vinegar. Seemed to "boil out" the trap and water sorta, kinda was flowing better, but still not great.
Then I had my Occam's razor moment, that the simplest explanation may apply. So laying on the floor and looking at the drain hose and DUH... it was clear why the sink was not draining very well.
When the trash container was put under the sink at some time in the recent past it pushed the drain hose such that what ever was once holding it in place was removed so the hose had popped up as an upside down U so the the highest part of this U was now inches above the sink drain.
Water could not flow easily uphill
. A quick fix with a zip tie put the drain hose back in place with the correct slope and all is right in Scamper land again.
