Pulsator fits on both our older style blue tank systems and our new systems housed in white units.
Pulsator rebuild kit sold separately.
The pulsator requires a good vacuum pressure to function correctly, so if one is not hearing the clicking in the pulsator, it could be an indication that vacuum pressure is lost elsewhere.
Please see our Troubleshooting Guide, which provides help for all of the systems we have sold.
We are happy to help with troubleshooting, just reach out through "contact us".
