Shurflo and freezing

[SeanD]

I use the 4008 12v Shurflo in three spots. The one on the S3 runs directly off a 12v marine battery. Two other set ups run off 110v power, but I still use 12v pumps. I use an old computer power supply to convert to 12v for the pump. It's an extra component in the box, but it's constant worry-free power and it beats hauling and charging batteries daily.

This is exactly what I was looking for!!!
I'm building a system right now and using a 12volt sureflo but want to run it off 110 power.
Are you using a temperature controller with your setup?
If so, do you have any pictures to share?

It's the two-stage Inkbird I have linked further up in the thread. My new box is ready to go. Now I can't find anyone with an old PC tower kicking around their basement! All I find in the e-waste piles are laptops and LCD tvs. Maybe I should go to an antique shop or, *gulp* buy one.

I have a tower you can have. You just have to drive out here to the Berkshires for it.

[SeanD]

Right, you know what's going to happen as soon as I buy one.

Putting together my shurflo setup for those who use a temp control do you use a electronic valve or do you just run the pump below freezing say minus 1 Celsius and have it shut off

I bought Black plastic tote boxes from HD or Lowes. When it starts to warm up they heat up faster than another color box. In 4+ years of using these Ive never had a pump freeze up and get damaged.

-1C should be perfect for you.

Do you use an electric valve the opens inline before the pump?

We put in a 15 watt bulb which keeps our box at 63 degrees. Our box is also covered with purple foam insulation

Do you use an electric valve the opens inline before the pump?

On my remote battery setup, yes. The S3 controls it, so when the temp drops, the valve opens - bypassing the pump to gravity, the pump runs for 10 more seconds to clear the pump and line. No light bulb, no freezing. Fully automatic. Just need to swap out batteries. The S3 is a great unit for a remote situations.

On my 110v plugins I use the bulb to keep things from freezing because once the pump shuts off, the line and the pump stay full of sap. I do have a valve just before the box, but that's so that I can clean the filter during a pickup without losing vac in the whole line. I'll show up, close the valve, shut off the pump, clean the screen, open the valve and turn the pump back on.

If there is going to be a multi-day deep freeze, I disconnect the box entirely and take it home. I'll leave the line open to gravity feed to the tank. Once the weather improves, the box goes back out.
