Hello all fellow TFPers,
Okay I am raising my hand with a "stupid" question but there are supposedly no "stupid" questions.
To turn the port valve when vaccuming or setting up pressure cleaner do I need to shut off pump before turning valve handles or can I just turn when pump is running. I dont mean the handle on the filter. I mean the ones that shut off my returns and direct to pressure cleaner line. I have been turning them with the pump running but saw the other day in small letters on the handle.."turn off pump before moving". Thanks.
