Thanks for this elerner61.

Just wondering if you remove the one-way plugs (pictured below) from the bottom of the drainage tubes -- either temporarily (only when blowing the tubes), or permanently (on the theory that they actually promote blockage and serve little real purpose)?

I've seen references in the posts that this plug is actually composed of two parts -- 1) an inner rubber piece that can be pulled free of 2) the outer plastic plug that actually inserts into the bottom of the tube, but that BOTH the plug and that inner piece should actually be removed so that there is no blockage left at the bottom.
Is this so? Picture does not seem to show any seam or separation?

Thanks
