Just wondering, how do you insert the wand in the gray tank, can't find any opeining in mine. Works great in black though. This ia about 20' stream, very hard for 10', easily cleans 7.5' length tanks. Oh yes, the concrete cover only holding it temporarily, thats a 90 and orifice cap on the end of the lance.
