Hi

Tried that ,but just end up having to leave a message and phone number and guess what ? no one ever rings back !

mike.

Any of you folks know how many gallons the inner (easy) circle in the nexus 300 holds ?

Mike.

is there a calculation for working out the loss of flow ?

I am now confused ! It doesn't take much !! where does the 2000 litres come into it ? and won't swept bends just increase the flow ?

Mike

Ok Jules will attempt to do that but will most likely be the weekend now

It has 6 x 2" 90 Degree bends and about 3 metres of 2"pipe from the pump to the pond ,the pump is an Optimax 15000 is fed from the Nexus right up to the pump by 4" pipe and has no other restrictions

Yesterday,drained it down removed all K1,removed it from its position had a good look around it ,turned it up side down! nothing appears to be abnormal. Purged bottom drain ,satisfied that there are no restrictions there. Put it back into position connected up and switched on,initially it ran as I w...

Hi Dave My BD is def set to a generous 2" clearance,I am expecting a long day tomorrow draining it down giving it a good going over ! I intend also to dismantle the pipe work back to the rubber boot and purge the drain to see what happens. I do know that up until I closed down this Nexus when I...

This suggests to me that the water is not transfer...

norfythenorf, How do you connect the nexus air ring to the rubber boot on the air pump ,mine appears to be a different diameter.I wondered because i have it clamped to the rubber hose if i am losing air pressure ?

how do you connect your air tube to the boot ?

Today i have taken out 50 litres approx of K1 made absolutely no difference ,it still doesn't turn over all the way around. Secondly I put on an old Aquamax 10000 in place of the Optimax 15000 the water level in the Nexus barely dropped an inch from the pond level

Not sure what you mean by "My starting point would be to double check that the domes haven't settled down on their stems. Pole with a suitable diameter stick at 90 degrees and you won't even get wet!!"

Mike

Hi again, I have completed your suggestions: With the pump off the water level returns to pond level almost instantly, with the level in the Nexus up the K1 Bubbles all the way around. I have back flushed as Jules suggested,switched back on and the level drops to as was. I am coming to the conclusio...
