Summary:
In many respects the most annoying part of putting a pond together is assembling all the right fittings to match up to the different pieces of equipment: pump, fountain, UV, filter inlet and outlet and so on.
Preferably use ribbed flexible hose if you can find it even though it is more expensive than clear plastic.
The most important reason is that this pipe does not kink and restrict flow and can therefore be used to go around obstacles such as tree trunks.
Pipe lengths of about 3 metres long will reduce flow from the pump by about 5% if the correct diameter is used.
Do not reduce pipe diameters by using reducers or clips unless absolutely necessary.
Avoid bends and especially right angle corners because they restrict flow from the pump quite considerably.
There are sockets (female screw threads) and adaptors (male screw threads).
So it is with fittings sit down and decide whether you want to have a hassle free pond or are you prepared to have hassles, if not now then certainly in the future.
The body of the pump has a female screw thread and if you measure the diameter of this thread it is 19 mm (or 3/4").
However if you go to buy a male fitting to screw into this hole you will need an adaptor with 1/2" thread.
Similarly the fitting for the larger FOCUS 3000L or 4000L pumps need a 3/4" adaptor even though the thread diameter is 25 mm or 1".
