If the valve is not blocked but seized, lubrication may do the trick.  GROCO offers 316 Stainless Steel Zerk fittings which can be used to pump grease into valves to help keep them lubricated and operating their best.  Proactively installing the Zerk before the valve gets stuck is the ideal solution.

The simplest way to identify your pump is to visit the Pumps Page or Water Pressure System Page and review the options.  Most pumps are visually very unique and easy to spot at a glance.

If the valve leaks past the ball then the seats may have become permanently damaged in which case the valve either needs to be replaced or in the case of the BV, SBV, SBV-P, and BVS models the seats  can be replaced.

For Paragon verify that the pressure switch is functioning properly by jumping the connection.  Also verify visual condition of circuits cards for obvious damage.  If a visual fault is seen call GROCO for further information.

Burner circuit contacts open after 15 second delay in a low water condition. Delay prevents short cycling caused by momentary fluctuations in the boiler water level. Automatically reactivates burner circuit 30 seconds after water reaches the probe, allowing optional water feeder to raise water level above the probe.

A-  Replacement parts can be found on our services sheets in the Service Manual Tab above or by navigating to the product in question in our Online Catalog and reviewing the exploded parts diagram.

A-   For the HC, HE, and HF this is usually a result of the inlet gasket failing and needing to be replaced.  Part# is HF-1.

A-  Verify the pressure switch is functioning by jumping the wires to bypass the switch.  Also make sure the air pressure in the storage tank is correct.

For the K-H it can be as simple as a stuck check ball or piston rings that have gone bad.  Call and speak to a GROCO tech for details.

If the toilet has a plastic pump off to the side of the bowl it could be a HC, HE, or HF.  All parts for these toilet pumps are interchangeable so please visit the HF-B page for parts information.  The only notable differences is that the old HC model has a two bolt gasket separating the bowl from the base instead of a three bolt gasket.

The simplest visual difference between the two is that the EB discharge bracket has four bolts while discharge bracket on the K-H has two.  The "K" is also cast into the side of the K-H toilet.

A-   If it leaks from the stem tightening the handle nut may fix address the issue.   The BV, SBV, SBV-P, and BVS valves have replaceable stem orings as well.

If simply adding grease does not help the BV, SBV, SBV-P, and BVS seacocks are field serviceable and can are able to have the failed components serviced or replaced while attached to the hull.

For legacy products please call 410-604-3800 to speak to a technician or email details and photos to info@groco.net.  We are happy to help!

A-  Check the condition of the impellor, gears, or rotors and blades.  This is the most common reason for poor pump performance.

A-  Trick of the trade!  Take a flat blade screwdriver and heat the end with a torch until very hot.  Carefully, quickly, and firmly press the hot screwdriver into the portion of the plug remaining in the strainer until a clear indentation has been made.   Remove the screwdriver, let cool, then use a screw driver to unscrew the plug in with the newly formed slot.

For the EB lack of prime can result from either a bad shaft or word diaphragm.  Call and speak to a GROCO tech for details.
