Water Pumps

[middoes]

I have a Run-to-waste setup witch feeds 8x300mm pots with 2 drippers in each pot.

 

The pump that i have running is a AQUA ONE 105 PUMP (2500L/H MaxH 2.6M)

Also the hose that joins the pump is a 13mm. Then the 4mm dripper hose comes of that.

 

The problem that i have is once the pump is turned off, the water still keeps pumping through for a while longer because of the pressure in the hose line i believe .

 

How can i stop the pressure.

At the moment this is forcing me go into the grow room every night, place the pump into the drum then once finished pull the pump out of drum( the drum is which holds my nutrients)

 

Any ideas,

set the timer to turn the pump off quicker watch it when the pump turns figure out how long the pump still has water coming out then take that time off the time your filter is on for...

either that or just hook up a aerator to the tubing then once pump turns off all your air being pushed down the tubing will stop the water flow...

[middoes]

Never heard of a aerator, Can you show us a pic or a link where i can see how they work.

 

Thanks Mattick

Is the water level in the drum higher than your drippers by any chance?

Hey Middoes, put a small relief valve any line e.g. a 1/4 sprayer on the outlet side of the pump just above the water line so it sprays into your ressie, this will deal with the pressure.

with an AIR STONES (RIGID) at the end of the hose.

When the drum is half full or more the water level is higher then the drippers. The drum is a 200litre
