I live in NC and have chosen NOT to close my ingroud pool. I leave my variable speed pump running continuously at a low speed. I'm worried about extended cold weather below freezing. Will incr

Even at low speed these pump move allot of water, I would feel better with the pump running on high. but most variable speed motors only run on high for a few hours and return to low speed. If you cant force the motor to run on high continuously, IF YOU can't run it on high= The wind chill is the concern, might I suggest covering the plumbing portion with a tarp, just do not cover the motor it needs air to cool the motor.
A $10 hot water heater blanket Google Search might work on your filter,and some plumbing insulation tape Google Search OR if it gets real cold you could build a temporary pump house out of say 2'' PVC and with 8 or more Concrete Blocks and some tie down straps to secure it down and cover the whole works with a tarp using some of the blocks to hold the tarp in place, this way the heat from the motor will keep it nice and warm inside your temporary pump shed, but this is only if you can't run the motor on HIGH continuously, low speed worries me with possible - minus 40 Degree temps.
also turn the pools jets up to keep the pools water from freezing up and turning into a skating rink.
IF you have a pump that only runs on high for a few hours you will need to set your alarm clock and get up and reset the pump to run on high again, just to be safe.
The pump creates heat by act of pumping water, so you have that on your side. ..keep us informed on your results as these variable speed pumps are fairly new to the market.
thanks .. Jay

I have a Hayward sp3400vsp. The pump runs all night some times, the screen say is priming, it will shot off manually, and it wont do it all the time. help??

Sounds like the pump is sensing that there is a problem with water flow on the suction side.

Could be caused by air being sucked into the system. Do you notice air in the strainer chamber? Or bubbles coming from the inlets in the pool?

Could also be caused by something clogging or restricting the suction line.

Will not stay running

Hi, Anonymous and the usual suspects are:
1. Idle speed improperly adjusted.
2. Inlet system air leak.
3. Leaking accelerator pump.
4. Loose low-speed jet.
5. Plugged low-speed jet.
6. Contaminated or plugged low-speed circuit.
7. Enrichner valve/choke not seated or leaking.

I have a Hayward sp3400vsp 2 HP pump for my in ground pool.When I turn on the pump it tries to auto prime for about 5 minutes and then shuts off. The pump is less than one year old. Any susgestions?

I have the same model pump. When I had it put in, the installer said that the auto prime function had some bugs in the software. He suggested changing the setting to 3 minute prime. You can change it in the configuration menu. I assume that your pump is actually priming and not running dry. Hope that helps. Please reply if you need more help. Good luck!

Pump will not run, electronics operate well

Can you plug the pump in directly to power and run it full speed? As this is an old problem, I'm sure you have already fixed it.

My new ecotouch pump will not pump. It is a week old and the problem has occurred today. The lights on the pump indicate that it has power, there are no error flashes, but the pump does not switch on. When...

I would check the correct voltage is being fed to the pump (220-230v). Otherwise call this guy at the company, he was pretty helpful to me. Remember you have a 2yr warranty.
