pond filter noise

~ janj wrote:
I have a submersible pump feeding an upflow filter. It makes an
annoying noise. The pump itself is silent and the sound of the water
flowing into the pond is pleasant. The problem is the sound of the
water flowing out of the filter. It makes a rushing/gurgling sound. The
water leaves the filter through a closet flange in the side of a
barrel. Can anyone offer a tip on how to silence it? It drowns out the
waterfall. Cam

A bigger opening from filter to waterfall may do the trick. ~ jan
-----------------

The water returns via 1 1/2 inch hose, the waterfall is fed by a
separate pump.

I don't have the ability to increase the size of the opening without
rebuildind the filter and replacing the hose. I tried jamming a piece
of filter material into the opening and the noise disappeared! the
water level in the barrell rose a little but now it all runs
silent.Thanks for the ideas.

Hi Cam - I have no idea what is causing the "noise" - I have built 40 - 50
upflow filters for customers and use a 2" return bulkhead and line and have
yet to hear about the noise you are talking about
the piece of filter material you jammed into the return line is an
accident waiting to happen as the filter material will load up and slow the
flow until your barrel overflows and pumps your pond down
Gale :~)

My first thought also. If OP can get to the opening/hose seems they could
enlarge it, perhaps with a heat gun and stretcher? ~ jan

It could be worse, janj. Your insides could be rotting and falling out
of your arse.

My first thought also.

I see, you're a coffee fiend.

I'm a VETERINARIAN. I do it with sick animals.

You really are sick, aren't you, janj?

It's different stages.

You're a little late. [Catching you by surprise]

I don't get it.

The water is siphoning out of the filter and makes a flushing sound as
it rushes out in pulses. I'm going to try lowering the whole filter to
reduce the height differnce.

AHH - does your return line have a "low spot" in it - i.e. - does it have a
gentle, gradual fall to where it discharges? - if there is a sag in the
line, that could cause a gurgling sound, and if the sag (or low spot) in the
return line is enough, it will overflow your barrel - the return line must
either be level or have a down slope with no sags

there is no low spot, it slopes gradually for 6 feet to the pond

A rebuild might be easier than keeping the filter material clean to
prevent the barrel overflowing. My water runs clear at this time,
but still clogs my finer filter material about once a week, and I'm
not dealing with 1 1/2" diameter, more like 20x20 filter with a flow
of 1200 gph.
