I wanted to remove the worst of the sediment from our garden pond so I
bought one of these dirty water pumps
http://www.screwfix.com/app/sfd/cat/...65041&ts=10082
(except from eBay - somewhat cheaper).
The blurb says it's for footings, ditches and ponds ("not small fish ponds"
so presumably OK for big ones ???). But the enclosed instructions say it
must not be used with water containing sand, clay, silt or mud.

What kind of dirty water from footings, ditches or ponds *doesn't* contain
sand, clay, silt or mud?

The reason for not using in fish ponds is that the lubricants used in
the pump are not safe for aquatic life, and they can't guarantee that
they will not leak out.

You sure they did not flog you the clean water version instead?

You can download the screwfix instruction manual he-

http://www.screwfix.com/app/sfd/cat/...5041&ts=10082#

In there it mentions no limitation on these materials other than
ensuring the total concentration is under 5%. It does say that sand and
other abrasive materials will shorten the life of the pump though.

Thanks - the Screwfix documentation is worded slightly differently to the
10-language generic booklet I received and is more forgiving. I definitely
have the dirty-water version.
