Applies 8070, HP60, HP120, 1000DX-200, 1001DX-200, 20-110, and older units with similar diaphragm pumps.

When installing a replacement diaphragm pump with a polymer pump head, special care must be taken to seal the threads with only a liquid or paste pipe sealant, and not to over tighten the fitting, in order to avoid cracking of the pump head.

Cracked pump heads will not be subject to warranty and cannot be returned.
