GHL Dosing 2.1

[SMI-UQ]

Hi,

I noticed that one of my GHL Dosing 2.1 was making a grinding each time one of the heads was activated. Is there any problem with it? What can I use to stop it?

Best,

S.M.I

Can you please test this pump by temporarily running it at a different speed? Does it still get stuck when manually activated?

How often do you have this pump set to run?

Hi,

I think it is more a squeaking sound (sorry for not using the correct word) coming from the head. I will try to run it at different speed and come back to you.

Thank you,
