As a tech junky, all info is appreciated!
When leak-testing, the DDC was powered independantly by an AT powersupply.
DDC was sooo quite... the low rpm fan from the PS was louder!!
Keep hoses isolated!!! that's what makes noise from an otherwise near silent pump!.

Wang,
The older pumps were taken out of the retail chain and the newer pumps are in the market place now.
Laing is a really great, top notch, company. They know pumps from the biggest to the smallest sizes.
