what size line for return to sump ??

[kenmac]

I added a return line to sump on my yanmar from outlet loader valve. I used 1/2" for the return . Should this line be 3/4'' ??

if you're not experiencing any undue noise or heat it's probably ok but rule of thumb is always make the return line from your valve larger than the inlet. you may not have enough flow to make a difference but if your not sure of your return line size err on the larger side of choices

don't know about the heat. No noise. Just didn't know if I was returning enough fluid with 1/2. I may try to make it larger ( if I have the room ) this winter.I believe I'm also returning some fluid through the 3 pt in addition to this 1/2' return line I added

Thanks
