My seawater pump for my a/c's quit working,replaced with same, little giant, name and size pump. Have 2 marine air units. Now when you turn the a/c unit 1&2 on with relay switch noticed that the relay clicks twice,first the control boards lite up then the water pump starts up. Never noticed it clicking 2 times before. Checked all voltage ok. Any idea's or is this normal and with old pump Could only hear clicked once, was that normal? Possible is that the reverse valve making noise?
