Creating a wash cycle - need code :)

[eisaiasjr]

Hello:

I have a 1 way valve on my return pump and I am looking to perform daily "wash cycles" on this pump once per day in order to flush whatever stuck on the weight and causing it to stick in the "up" position.

Basically what I am looking for is code that will cause the pump to turn on and off 3-4 times for a period of 5 seconds in between intervals.

In other words the return pump should be ON AT ALL TIMES but 1 time per day (1pm) I want it to turn OFF (5 sec wait), then ON (5 sec wait), then OFF (5 sec wait), then ON (5 sec wait), then OFF (5 sec wait), then ON (5 sec wait), then OFF (5 sec wait), then ON for the rest of the day till the next wash cycle.

If anyone can guide me with this request it would be highly appreciated.

Best Regards,

Estefano

This will get you kind of close. The oscillate will cycle 5 sec on, 5 sec off but only between 13:00 and 13:01:01, so you would get 12 on/off cycles in that time. You can tinker with the timings.

Fallback ON
OSC 0:00/0:05/0:05 Then ON
If Time 13:01 to 12:59 Then ON

Depending on the make and model of you return pump, it might not be a good idea. Most return pumps dont like being turned on and off on a regular basis.. That can cause premature failure of your pump. If you are getting stuff stuck in your pump, that would be the issue I would address. Clean your sump or add some sort of a prefilter to stop any debris from getting into it.

I considered this, its not the pump that has the issue (its an eheim 1262) its the 1 way valve that gets stuck on the "up" position when I turn off the pump to service the sump.

I will however change the programming so that it will only do 3 on/off cycles by changing the timing to 10 secs

--- This is the actual code on my system ---

Fallback ON
OSC 000:00/000:10/000:10 Then ON
If Time 12:30 to 12:28 Then ON
If FeedA 000 Then OFF

The issue is likely the result of calcium build up on the inside of the valve. It happens over time and I too have the same issue with several of my ball valves. Matter of fact, its common even with brand new valves. When ever I purchase any new valves for my tank, I always open and close the valves before I buy them as some are sticky due to the manufacturing process or lack of quality. Its just the nature of these ball valves. If its a big concern, a gate valve can be much more reliable and much less trouble opening and closing.

I would not suggest messing with the pump like that as you will end having issues with it and it wont help your valve issue. Sadly, I dont think there is much you can do. If you are really concerned, get a double union ball valve that can be easily serviced. You would have to plug the return bulkhead when it needs servicing so that water doesn't siphon but then you would at least be able to service it.

Sounds like he is using a check valve and it is getting stuck in the open position.

yup, using a George Fisher Wye check valve
