Hi. I'm planning to use a pump to water a plant. I want to install a hose from the pump to the plant and to close at edge of the hose there, then to perform small holes into the hose so the water will come out gently through several holes and around the plant. My question is if the pressure generated by having the edge of the hose closed, wont affect somehow the pump?
Thanks a lot!!
Depends on the pump. Some may burn out quickly if forced to work at high back pressure.
Look carefully at the pump specifications before deciding, and research drip irrigation.
Drip irrigation is common. Size the pump to your daily flow rate.
Hi. Thanks for the answers. The pump is this one. This pump is connected to an automatic/manual system that measures the soil humidity, so it depends on where is localed the soil and it's probe. If the place is indoors, then the pump would be used less often, like once a week, but if it's outdoors, then it could be even daily.
Could I perform a number of little holes equivalents to the diameter of the pump's way out and, then, to test by putting my finger to the end of the hose; if there is low or zero(?) pressure then the pump would be fine? The hose must have pressure for the dripping to work (by closing the end of the hose), if the little holes are enough, wouldn't this be just like an extension of the pump's way out?
That pump doesn't seem to be self-priming, so you will need to keep water in the pump and the tube to reservoir at all times.
I agree with Paul_KD7HB that it appears not to be self priming. To resolve that question place the pump below the water reservoir, it then becomes self priming. You should add a small float switch to be sure the pump turns off when the water is low.
And will leak water through the output tube because there is nothing to stop the water! Bad design for an irrigation system. At least one valve is needed in the output tube to stop the leaking.
Could you mount your header tank high up and use gravity ?
Yes, that's the idea: the pump's weight makes it to go to the bottom of the tank, from there it seems to work fine by pumping water through the hose.
I had not thought of what would happen if the water runs out. I've thought one would refill the tank if its level is low. I'll keep in mind the small float switch idea, to protect the pump.
Yes. As I mentioned in my first post, the idea is to close the end of the hose (with fire), so the water will be forced to come out through the holes that I make.
They system has a soil humidity sensor, so its going to turn off the pump once the soil is wet.
This implementation is first meant for indoors, by using a small tank, like a carboy, that could handle a very small cultive. So, I wouldn't be sure about installing the water tank high up in a livingroom, a pump seems more practical I think.
Thank you all for your answers!
If you are all set to go, then that means you have the pump and can ignore that fact it is no longer available.
That doesn't look like a submersible pump, are you sure of that?
You're right!. I totally forgot about it, as I haven't used it in a while. Yes, it goes on top of the tank (it could be aside too) and has two hoses: one goes to the tank and the other to the pot / cultive. Thank you.
IF you are REALLY using the pump that you pictured, it is submersible, based on the Amazon web page. How will you keep the pump primed if it goes on top?
Not if it has an air gap above the water level, easy to accomplish if there is no back pressure.
Yes, You're right, I got confused, I apologize. The pump is submersible!
