Title: air locks on flat tanks
Post by: Carl@Cwc on April 19, 2013, 10:09:06 pm: looking for some ideas really?

constantly getting airlocks with our layflat tanks , is there an easy fix /solution to clearing these?
i saw on a grippa tank install someone had managed to install something to clear them quickly and without mess?

any help appreciated.

i plan on refitting an upright in new vans as the airlocks are a daily nightmare unless an easy fix is out there?

Even when empty and fill up I don't get any.

these are the ones i have used, as all my tubing is house grade 22mm down to 15mm to pumps
