Title: Sureflo pump airlock
Post by: marcus hopkins on February 23, 2007, 07:05:25 pm: Hi

I have had my WFP for 3 months now. The only complaint i have is that my pump gets an airlock 3-4 times a day. Do others experience this problem? Is there a cure? or does anyone know of a way to perhaps install some kind of vessel to capture the air before it reaches the pump? These pumps are supposed to self prime, surely that means that it should expell any air when it tries to draw the water.

Some where on the inlet side of your pump you are sucking in air, tighten all clips up and see if that helps.

thanks for the replies. My connections are all tails with the pipe jubilee clipped on. I was using my system in a static site the other day, van not moved at all and still managed to get 3 airlocks.

Post by: marcus hopkins on February 24, 2007, 06:36:43 pm: yes the pump is higher than the tank as i was told that it didnt matter. I'm starting to see i may have been misinformed

Post by: Clive McDonald on February 24, 2007, 06:44:47 pm: I'm no expert and I was hoping that someone that knew what they are talking about could advise me on this.
But in that case( your pump being higher), once air has got in, it must be impossible for the pump to draw water.(I think)

Post by: peekeclean on February 24, 2007, 07:02:44 pm: marcus what is your set up? as i had this problem with my set up and it was a combination of useing stop connectors and haveing the water comeing out my tank(in van) into my di then to the pump.
now it gose out my tank in to the pump then through my di, had no problems since.
and believe it or not it was well known supplier who advise it the wrong way(no names) hope this helps.

Post by: Londoner on February 25, 2007, 08:22:40 am: My trolley system airlocks all the time but it clears if I turn the varistream up to max and give it a blast for a minute of two. This is a problem that won't go away because I introduce air into the system every time I change a water container. The higher the pump is above the level of the water the more this is likely to happen.
