Tube for a 29mm bilge pump??

[Airscrew]

Last year I bought a SeaFlo 1100gph bilge pump. Still unused.
Principally because it has a small footprint for my narrow bilges.
But I should have checked a few other things, but, well, here we are.

It requires a 29mm ID hose.
In Force4 this week I found they dont have 29mmID hose.
The assistants were not able to help.
Odd, as other pumps also need 29mmID.
Infact, online, I cant see any chandler/supplier of 29 hose, other than washing machine outlet.

Also, the boat has existing 19mm pipe to the throughhull, which I dont want to change.

Far too late to return the unused pump (dont have the receipt anyway)

So,
Any suggestions please for suitable pipe/tube, plus, a converter from 29 to 19mm??
Oversize plus a (pair) jubille clips??
And how to convert to 19mm??

Thanks in advance.
Jonathan.

29mm hose is 1 and 1/8th inch and is not that unusual. It's sometimes converted to 28mm. (Multi-Purpose PVC Hose 28mm ID (General Purpose Hose)).

If you look through their catalogue you should be able to find a reducer. I'm sure Vetus do them where you trim them to the needed sizes.

Or best is to increase the size of your outlet so you get the full benefit of the pump you've bought.

Is it not possible to use a 1 1/8 hose (id 28.5mm)?
If so, Vetus makes a stepped adapter which includes 28.5 and 19mm.

28mm is I guess the clue I was looking for.
Many thanks to you both.
