Plumbing Help

I'm doing a little plumbing for my filter system based on some
inspiration
from Netmax's website. OK, I'm stealing it wholesale. I even printed
out
his sketches to work from. They say plagiarism is the sincerest form
of
flattery 8-).

The problem is: I'm working with 3/4" PVC, 3/4" hose barbs, and 3/4"
hose.
Unfortunately, my Ehiem 2026 uses 5/8" (16 mm) ID hose. Of course, I
missed
that little detail until I had the whole thing built up. At least I
don't
have it all glued together yet. I was at least smart enough to do a
fit
check.

I don't see a way to convert the filter fittings to 3/4" (19 mm), and I
have
not been able to find 5/8" hose barbs in PVC. I'm pretty sure I could
turn
down the 3/4" hose barbs to fit 5/8" hose if I still had access to a
lathe.
The fittings on the filter do not look like they will work with a
bigger
hose, and Eheim does not seem to offer a version that accepts larger
hose.
At this point I am pretty much stumped.

Has anyone else solved this problem? Any suggestions from the peanut
gallery?

A couple ideas to try, both use a section of hose. One is expanding the
16mm ID hose around the 19mm OD barb by dipping the hose end in boiling
water for a minute. The other is to get a hose adapter. Check out a
Laguna display at a large LFS (a small LFS might have too small a Laguna
display and not carry enough of their parts). Other pond equipment
suppliers may have the parts I'm thinking of. Because of the variation
in pump fittings and hose diameters, manufacturers have these universal
connectors or a series of adapters for the range you are looking for.
Laguna in particular has 3 quick-click connectors which have a stepped
tang for 3 hose sizes. If one has the two steps you need, just cut off
the quick-click portion. More expensive than an adapter, but less work
than a lathe. Do give the hot water a try. This is quick cheap and
effective. hth
