Model Trimmer Waterline Replacement Made Easier

Do you have a Whip Mix ½ HP Model Trimmer? Replacing the waterline to the solenoid or electric water valve on the ½ HP Model Trimmer used to be somewhat challenging. It involved placing a brass threaded ring over a plastic ring that encircled the waterline hose. The ring combination prevented water leakage.

The challenge was that, with the multiple parts, it was sometimes difficult to install properly. If it wasn’t, it had the potential to leak. (Fig. 1).

The current water inlet hose connector is much simpler and very unlikely to leak once installed – even for users that may not feel comfortable doing  plumbing work. The connection involves only one Prestolok Male Connector ¼” MD5340 item# 09835 (Fig. 2).

Simply push the black hose into the green ¼” quick connect opening. The hose will still turn freely but maintain a watertight connection (see Fig. 3).

Ensure that Teflon tape covers the threads before connecting, to allow the best seal possible. Simply screw the quick-connect fitting into the brass column of the inlet side of the solenoid. It is usually designated by “IN” or a “1” inscribed near the hole (Fig. 4). If the hose has to be released, push down on the green ring toward the fitting and pull the hose to remove.
