Maintenance Instructions

Cleaning

Trionic Corp's roto-molded polyethylene products (dock boxes, dock boarding steps, marina trash cans, and water tanks) are built to be long-lasting and require low maintenance.  For the products typically used outdoors, UV inhibitors are included to maintain a bright white appearance.  The smooth finish of these products also makes cleaning them quite easy.  We do recommend that you occasionally wipe down your dock boxes, steps, and trash cans with a damp cloth to keep them looking great.  If your run into any stains or dirt that isn't easily removed, we recommend an environmentally safe cleaning product that won't have an impact on the water quality around the docks.  There are a number of different cleaners available that fit this description, but an inexpensive product like Simple Green Marine All-Purpose Boat Cleaner is a good choice.  

Broken Hinges or Cables

If you run into an issue where a hinge or lid retention cable becomes damaged, replacement parts are available to quickly and easily repair the product.  Swapping these parts only requires a wrench and a screwdriver and can be completed in a matter of minutes.

Leaking Fittings

Always inspect fittings to be sure no cracks or breaks have occurred and replace fittings as needed.

If a threaded fitting is leaking, we would suggest adding Teflon tape around the threads and reseating the fitting.

If a compression fitting is leaking, it may need to be replaced.  The condition of the edge of the hole in the tank should also be inspected to be sure a clean square cut with no burrs or rough edges.

For a leaking deck plate, you can add silicone sealant under the deck plate flange.  Be sure to remove any old sealant before applying new sealant.  

Vacuum Relief Valve

If your vacuum relief valve is stuck, unscrew the cap and check the rubber disc. Put some Vaseline under the rubber flapper where it sits up against the white plastic.

Cracked Water Tank

For a hairline crack in a polyethylene tank:

1. Drill 1/8" hole on both ends of the crack.

2. Scrape out a 1/16 to 1/8 deep V-Groove in between the 1/8" holes.

3. Cut 1/8 diameter polyethylene rod to fit 1/8 holes and groove.

4. Use the blue tip of flame from a propane torch to just touch the groove and pass across 3 to 4 times to warm up the surface.

5. Position the rod into the groove.

6. Use the torch to heat up the rod until it turns clear and then use a putty knife to push the soft rod material into the groove. 

7.  Allow to cool and check to see that the crack has been sealed.  If not, you should replace the tank.
