Ballast Hosing
 

I have a Straight Line Sumo pump to fill fat sacs. Unfortunately the hosing tore this weekend so I need some new hosing. I can reattach the quick connect connector from the old hose to the new hose. Is it just 1/1/8" PVC hosing that I need? And can anyone recommend places to look in the UK? Check chandlers? The wakeboard shops that I can see only sell whole pumps which I don't need, and the hosing I found when I googled it was in the US with crazy high postage! Thanks!

I'd stay away from 1-1/8" hose unless you absolutely have no other choice. Connections and fittings are almost impossible to find unless you order them online. stay with 1" you can pick up anything for it at local hardware store to fix it on the fly.

Marine standard bilge pump hose is 11/8"
Quite available.
Fittings? not so much but hose certainly is.

every bilge hose i've seen on a towboat is 3/4".

built my last system 100% with parts from local store. replacing something, go with whatever you have in the boat. built-in system? If you're throwing a pump over the side, its likely 1". Throw a micrometer on it to see for sure. usually measured by inside diameter.

Who the heck said tow boat?

Oh.. you did.

Most general hose manufacturers will have what you want. Some of the hose in my boat (which is identical to the wakemakers one) came from a shop that supplies industrial users.
