Have 2 di vessel's one  has small connections coming from the head than the other. Does anyone know the type of thread and what the diameter of them would be,  I'm assuming they are standard sizes.

You have two types of DI Head's on the market, 3/4" BSP and 1" BSP.

If measure the diameter of the whole it is follows:- 3/4" - 1" DIA, 1" - 1 1/4" DIA

So I'm not the only one getting confused with different size ports! The new DI vessel I have just bought appears to have 1" diameter ports, but my old one is 3/4" . Where do I get 1" dia. male connector to JG pushfit? Trying to find these online is like looking for a needle a haystack. Cheers

Most plumbing suppliers will be able to supply these reducing bushes - they might be galvanised though.

A marine outlet (chandlery) will carry stainless steel if you have one close by.
