- I intend to replace my existing Salamander pump (positive head though) with this negative / universal pump and my current pump has 15mm pipework.
Hello
It depends what negative head pump your going for, Majority are in 22mm but there are 2 pumps which come in 15mm if you would like to give us a call on 0191 5162002 we can run through all this with you.
