SRC Member ervine Posted October 23, 2005 SRC Member Share Posted October 23, 2005 why not just get a DC pump? If you do then it's really easy... if i'm not wrong car windscreen wipers use DC water pumps (tiny ones) Quote Link to comment Share on other sites More sharing options...

SRC Member garyjg Posted January 19, 2009 SRC Member Share Posted January 19, 2009 Bro, what's the problem in making the top-up box? I've made two and they run AC pumps, a simple reply is what I used. either 12 or 24VDC... the supply for the reply is an old changer from a house phone.

SRC Member johntanjm Posted January 20, 2009 SRC Member Share Posted January 20, 2009 hey gary, is a relay really necessary? I'm halfway through building one.

SRC Member garyjg Posted January 20, 2009 SRC Member Share Posted January 20, 2009 hey gary, is a relay really necessary? I'm halfway through building one. if you want to use a cheap power head (240vac) to supply water to your sump... I actually used two relays, one for the low water level and the other relay kills the top-up box if the float sticks in a fill position (preventing flooding the floor).

aquaticlover Posted January 22, 2009 Share Posted January 22, 2009 hey gary, is a relay really necessary? I'm halfway through building one. Yea, relay is needed to isolate power supply from float switch and supply for the pump to get the stable current flow to the float switch. Those float switch need stable current to maintain their lifetime. Just my 2 cent knowledge. Quote Link to comment Share on other sites More sharing options...
