After I (not the same type, Intex standard at Poolset 3.5m) have replaced the pump against my old pump, I was surprised that my water was entering the water outlet. So I controlled the ports, and lo and behold, I discovered that the suction directly goes in the pump, and then the water is only filtered before it goes back into the pool. For me illogical, or just have a connection error (power supply) from the company Intex (for transformer can the cable only in a tuck position (foolproof)) ??? But will there nachbelesen me again. - I have just been at Intex question. Unlike the old standard Intex pump is just as loud, despite min. double power - so OK. With the appropriate adapters I could well go on to my 32mm hoses without making larger the holes in the pool.
Everything until the question is resolved in all, only 3 stars.
