well-water irrigation system

Hi -
Late last year I had to disconnect the line that goes from the pump to the pressurized tank on my irrigation system. Looking now to reconnect it, and wondering do I need to make sure there is no air in the system when reconnecting it? And if so, how would I go about doing that?

Thanks,
Brian

I am not entirely sure I understand your question here, but It sounds like you have a submersible pump for the house water and you have a bladder tank as well? They are usually blue and are round on the top.

Is there any way you can take a picture of this... might help me to better understand and help you.

Hi and thanks for the response -

No, this system is a irrigation-only system. I understand from the locals that there are a number of the homes in the neigborhood with the same setup. The pump unit is under the deck in the backyard so sor of hard to get a picture of, but I'll try to describe it. The pump head is about 16 inches or so in diameter and about 14 inches tall. There is a run of pcv pipe coming out of it that tees into a line that in one direction goes(went) to the pressurized tank on the other side of the garage wall, and in the other direction I presume it goes to the irrigation main control valve.

What is a bladder tank? The tank I have is blue but oblong shape. Hope that clarifies it well enough.

Thanks,
Brian

If you just have a pump connected to a bladder tank then there is probably a union connecting the two. I will be something you tighten with 2 plastic or metal "nuts" that tighten over a piece of rubber.

Your bladder tank will have air in it for now and there is probably a small tube on the back of your pump going to the top of the pump, near the impellar case.

The pump will run until your pressure has been reached and then will shut down. So long as you are not using this for drinking purposes then you can simply reconnect the tubes and fire up your pump as you normally would.

If you have never primed a pump before I can try and describe it to you but if it is done wrong, could destroy the pump entirely so do not attempt it if you are not certain what you are doing.

The bladder tank will automatically fill when you run your pump with water. The air will be pushed out of your first sprinkler zone you run.

You mention I can hook it up without concern if just for irrigation, but then mention priming? so, do I assume correctly that the priming issue you mention is only if the usages of pump include drinking water?

Thanks

You always must properly prime a pump. If you run a pump dry you will melt the impellars and that costs around $400 and up to fix.

This may help you prime your pump. Try this.
