What is a fill dish?

The fill dish is located on the outside of your unit so that you can easily add water to your tank without the need of opening a compartment or climbing under your unit. You can find the fill dishes in the Plumbing Category.

For adding water to the Water Tank you need a Gravity Fill Dish, the hose rests in the port it does not screw onto the port this allows you to place a garden hose into the Gravity Fill Dish port without making a sealed connection so the supply is not pressurized.

For using Water Directly from a garden hose you need a City Fill Dish, the hose makes a sealed connection and the water supply is pressurized, you can not hook this to your water tank and you do not need to go through your water pump.

We carry Gravity Fill Dishes, City Fill Dishes and Combo Fill Dishes that have both gravity and city, the benefit of having both is you can have a water tank of fresh water but if you go to a location that supplies pressurized water (campground - fair - etc.) you do not need to use your water tank supply of water you can simply use the water provided. Be sure to look at the provided example plumbing diagram for more reference.

EXAMPLE ONLY Your set-up will vary by installation

Due to increased sales we are no longer able to offer custom fittings on water tanks.

If you are a manufacturer or OEM needing custom fittings please contact sales for more information, minimum quantity of 50 tanks will apply.

The pump can be mounted at the same level or below the water tank, it may be positioned above the water tank if needed as it is capable of a 6 foot vertical prime.
Horizontal inlet tubing will allow priming to 30 feet.

Consider a dry location to allow easy access if maintenance is required. The pumps should not be located in an area of less than 1 cubic foot unless adequate ventilation is provided. Excess heat may trigger the internal thermal breaker and interrupt operation. When the temperature drops the breaker will automatically reset and pump will run again.

The pump can be mounted in any position if mounting the pump vertically the pump head should be in the down position.

The mounting feet are intended to isolate the pump from the mounting surface, over-tightening, flattening or use of oversized screws will reduce the ability to isolate vibration and noise through the lines.

The pump should be on a dedicated individual circuit protected by the specified fuse indicated on the motor label.

A U/L, CE etc approved marine duty (ignition protected) switch rated at above 15AMPS is recommended and must interrupt current flow on the positive (+red) lead.
The pump must be grounded to a known ground (battery). The ground wire must be the same size (gauge/Mm2) as the positive wire.

Proper wire sizing is required for good pump operation, if the wire is too small low-voltage will affect the pump performance and could create a fire hazard.
The total current draw on the circuit must not exceed 15AMPS. If the pump is used in conjunction with other components, overload current protection (fuse or circuit breaker) and wire size must be for the total amp requirements of all devices on the circuit.

We recommend at least 1 foot of .5" (1/2")i.d. flexible high pressure tubing to both ports. Ideally the pump's ports/strainers should not be connected to plastic or rigid pipe. The pump's normal oscillation may transmit through rigid plumbing causing noise and possibly loosen or crack components.

Installation of a 50 mesh strainer such as 51S01 series is recommended to prevent foreign degrees from entering the pump. Hex/swivel barb fittings provide easy removal if maintenance or access is required. The fittings are designed with a "taper seal" creating a water tight connection when hand-tightened. Always secure barb tubing connections with properly sized stainless steel clamps to prevent leaks, never use Teflon tape or sealing compounds on threads. Sealer may enter the pump causing a failure failure due to foreign debris and is not covered under warranty.
