The bottom drain has a 2" opening on the bottom and is connected to
2' of 2" pipe. From there it connects to a 4" elbow - 4" pipe - 4"
elbow - to 9' of 4" pipe to connect to the settlement chamber. So
except for the bottom drain itself it's all 4" pipe. The pump is a
Sequence 4800. The only problem so far is that the flow rate is a bit
fast for proper settlement so I'm playing with the adjustment valve
connected to the pump. So I've certainly got some decent waterflow.

Do you happen to know the best layout for media in a settlement
chamber?

DesertPond,

Do you get good waterflow to settling chamber using 4" pipe
reduced to 2" for settling chamber??

I was wondering what size pump you have from the settling chamber??

I have the same hook up. I used 2" pipe all threw to settling chamber.I have
a Sequence 3600 pulling from settling chamber.I had to add another 2" pipe
with basket on end from pond to settling chamber to keep up the pump.I
wanted 2000 GPH threw pump??

Thanks
Doug

I neglected to place a bottom drain in my pond last summer and have
regretted it ever since. So over the last week I added a Tetra Vacuum
drain retrofit to the pond. Seems to be working exceptionally well.
The photos of the upgrade are here if your interested

A bottom drain will make cleaning a heck of a lot easier and improve
the overall health of the pond.

I'm planning a pond. The books say 'put in a bottom drain to make

easier.' The (few) people I've actually spoken to say 'don't put a hole

your liner - don't need a bottom drain.

I plan for about 1500 gallons, 24-30" depth. Probably no Koi, because
I've
heard they generate a lot of waste (and get huge).

What's the feeling on bottom drains?
