help - deltec ap851

[dnsfpl]

got a brand new deltec ap851 yesterday

installed everything and start to feed water

check for leak and everything seems okay

but once i on the needle wheel pump, its very noisy, more noisy than my reef octopus

is this normal?

thanks

[Harlequinmania]

Is it a brand new set or used ? Better Check the aquabee pump and shaft..

[dnsfpl]

its a brand new set, with ehiem 1620 pump

is there anything i have to remove from the pump?

thanks

[ReDDeviLs]

i think its air trap inside,did u run it for awhile?

after the air all escape shld be normal already.

[dnsfpl]

i have dismantle the needle wheel pump and reassemble back

it doesn't resolve the problem

will let it run for a day, if problem still persist will call reef depot later

how long does it take to "run in"?

thanks

is the foaming pump producing lots of bubbles? close the air valve,then open it after u start the foaming pump

dnsfpl,

I think what your hearing is the air getting sucked into the pump; did you put the air valves on the lines? Also, open the air valves to about 2 o'clock for a good skim.

On the reef octopus you have a noise damper on the air inlet, put that on the Deltec airline and all the worries are gone.

Another thing you may want to take note. The pump may produce a lot of noise if the air valve is more than 50% close.

i second this!

If you have to close the air valve >50%, reduce the water level inside the skimmer by adjusting water outlet valve

[dnsfpl]

my air valve is always fully opened, align with the air tube

must i perpendicular it and then parallel it against the air tube?

thanks

[onizukaa]

bro try take a pic of the air valve maybe it will help for those who got the deltec skimmer.

[dnsfpl]

thanks all

[thomas_lim]

This is considered fully open. It is strange to have noise then.

Likely trapped air in the pump. Try to turn pump on and off 2 or 3 times to dispense it.

If noise still persist, call RD.

P.S. Alwso noise level is very subjective, so it could be the efficient of the suction.

[dnsfpl]

the "noise" is getting lower and lower

thanks all for the input

cheers

[onizukaa]

that's great to hear!

happy using your power pack skimmer bro! :D:D

(i want to get it too T_T)

[dnsfpl]

thanks bro

I don't like the sound of the occasional rattling that i hear from the video. same sound when there is no water in the pump.

[[V]tEc]

quite noisy leh. not like the one i heard b4...very silent compared to the one in the video

The occasional rattling noise don't seem normal.

Give RD a call and see if they can help.

Mine doesn't have this rattling noise. But your skimming is definitely more "chio" than mine.
