The burks WC-3 QWC-3 series household sewage riser toilet lifting device

Applications

The burks household sewage lifting unit (a Sino-foreign joint venture product) is suitable for places where sewage cannot be discharged directly to the main sewer by natural gravity. With the C-3, WC-3, CWC-3 and QWC-3, a toilet, shower, washbasin or other sanitary ware can be installed very conveniently anywhere in a basement, on the ground floor, in a kitchen or in an attic, because the C-3, WC-3, CWC-3 and QWC-3 can convey the sewage to the sewer pipe; they also make it possible to install a shower and a toilet far away from the sewer pipe, saving the cost of installing sewer pipes.

Places of Use

Air-conditioning condensate conveyance; additional bathrooms; washrooms under stairs; simple bathrooms in holiday homes; bathroom renovation in hotels; washrooms and kitchens in basements; setting up dedicated washrooms for the elderly, the weak and the disabled; relocation, addition or renovation of washrooms in offices and commercial buildings.

Function

The sewage produced enters the connected C-3, WC-3, CWC-3 or QWC-3 through the connecting pipes; once the liquid level reaches the start level, the pump in the lifting unit starts running and discharges the sewage, and when the liquid level falls to the stop level the pump stops. The tanks of the C-3, WC-3, CWC-3 and QWC-3 are made of light plastic material, are easy to clean, and run automatically and maintenance-free when correctly installed.

Model Designation

Example Q WC -3 X: Q = heavy-duty large-capacity type; connection: C-3 = no toilet connection port, WC-3 = rear-outlet, connectable to a toilet, CWC-3 = side type, connectable to a toilet (for concealed installation); 3 = 3 connectable maximum water ports (number of inlet connections); X = WC sewage inlet at the bottom.

Construction

The C-3, WC-3, CWC-3 and QWC-3 are tanks with a built-in pump; different models are designed for different applications and their structures also differ. Impeller: the impeller of the built-in pump is a semi-open impeller made of composite material. Inlet filter: a filter screens the sewage discharged from the toilet, and the cutter in the filter shreds toilet paper and faeces so that they can pass through the filter holes (Φ15 mm) and be discharged. Cutting system: the WC-3, CWC-3 and QWC-3 have a cutting system including a blade rotating at the bottom of the filter; the blade is connected to the motor shaft end and fixed by an elastic retaining ring (note: it can only cut faeces and toilet paper, not hard objects or hair).

Operating Mode

The C-3, WC-3, CWC-3 and QWC-3 are designed for intermittent operation, i.e. the pump runs for a short time and then stops.

Electrical Protection

The motor winding of the C-3, WC-3, CWC-3 and QWC-3 is connected to a temperature switch, which ensures that the power is automatically reconnected after the motor has cooled effectively; the cooling time depends on the ambient temperature, and no additional motor protection is required.

Ambient Temperature

The C-3, WC-3, CWC-3 and QWC-3 can operate normally at normal room temperature (maximum temperature not exceeding 40 °C); if installed in a place where frost is possible, take protective measures to prevent the machine from being damaged by freezing.

Siphon Effect

If the sewer connection is below the bottom of the C-3, WC-3, CWC-3 or QWC-3 tank, it is recommended to install a vent valve to prevent the siphon effect.

Connected Toilet

Note: the toilet connected to the WC-3, CWC-3 or QWC-3 must be of the horizontal outlet type, and each flush must be no less than 6 litres.

Connected Shower

Note: the outlet of the shower must be at least 120 mm above the bottom of the C-3, WC-3, CWC-3 or QWC-3 tank; note: it is recommended to install a filter at the grille of the shower drain outlet to filter hair.

Inlet Connections

All pipelines entering the inlet end of the C-3, WC-3, CWC-3 and QWC-3 must have a downward slope of 3%.

Curve Conditions

The performance curves in this catalogue depend on the pumped liquid, viscosity and speed as follows. The pumped liquid performance is measured based on: test liquid pure water; water temperature 20 °C; kinematic viscosity 1 mm²/s (1 cSt); the conversion between head (m) and pressure (kPa) is based on a water density of 1000 kg/m³. The performance curves in this catalogue cannot be used as guaranteed curves.

Introduction to QWC-3

The QWC-3 is a heavy-duty large-capacity automatic sewage lifting unit with a built-in cutting system, suitable for places where sewage cannot be discharged directly to the main sewer by natural gravity. Applications: mainly for discharging sewage from toilets, bathtubs, showers, washbasins or washing machines in basements below the main sewer into the sewer. Ordinary small sewage lifting units suffer backflow of sewage when conveying large-flow liquids from bathtubs, etc.; the QWC-3 handles this easily and is not afraid of backflow. It is suitable for pumping the sewage produced by showers (or washbasins), and can also pump sewage containing faeces from toilets (if the pumped liquid contains other hard objects or hair, faults may occur; such cases are not covered by the burks warranty). Pumped liquids: sewage produced by showers (or washbasins); sewage containing toilet paper and faeces from toilets; maximum permissible liquid temperature 40 °C; water for cleaning showers (or washbasins) and toilets; permissible liquid PH value 4-10; strong chemical solvents are not permitted.

Installation Brief

Installation introduction: the outlet hose of the C-3/WC-3/CWC-3 can be cut to the actual pipe diameter; the QWC-3 is of a fixed size with a 25 mm inner hole and needs no cutting; the outlet pipeline of the C-3/WC-3/CWC-3 should be laid vertically first and then horizontally, and when laid horizontally a minimum gravity slope of 3% must be maintained; the outlet pipeline of the QWC-3 should be laid vertically first and then horizontally, and when laid horizontally a minimum gravity slope of 3% must be maintained. Installation points: 1. The material of the outlet pipe must be suitable for untreated sewage and of standard pipe diameter; 2. The lifting pump has its own check valve, so there is no need to install a check valve on the outlet pipeline outside the lifting pump; 3. A shut-off valve should be installed on the outlet pipeline for later maintenance and overhaul of the lifting pump; 4. When the horizontally laid pipeline is too long, it is recommended to install a vacuum breaker at the highest point to speed up the discharge of sewage; 5. It is recommended to use 45-degree elbows instead of 90-degree elbows.

Troubleshooting

1. There is water in the pump body and the water level is above the start level line, but the lifting pump does not start
a) The power cable is not connected → Connect the power supply
b) Short circuit; if it always short-circuits, the wires or the motor are faulty → Check the short-circuit protection and test the power cable and motor
c) The motor has short-circuit protection; when the motor overheats, the thermal overload switch disconnects → Clear the overload fault, cut off the power, and wait 3-5 minutes until the thermal overload switch resets
d) The level switch is faulty → Replace the level switch

2. The motor hums but does not run
a) Check whether the impeller is entangled → Remove the entanglement and turn the impeller by hand
b) Motor problem → Repair the motor
c) Capacitor problem → Replace the capacitor

3. The motor runs continuously or runs at intervals
a) Water leaks from the inlet into the unit → Check the connections, replace the connections or reinforce them
b) Water leaks from the discharge pipe back into the unit → Check the internal check valve
c) The level float is faulty → Overhaul the level float

4. The motor runs but does not discharge water
a) The pump is blocked → Clear the blockage
b) Air in the pump → Check whether the vent hole is blocked
c) Blockage discharged from inside → Clear the blockage and check whether the check valve is clean
d) Blockage in the discharge pipe → Clear the blockage

5. The unit discharges slowly
a) The filter is blocked → Remove or clean the filter
b) Air ventilation is obstructed → Check the operation of the vent valve and check the carbon filter
c) The discharge pipe is inserted too deeply into the discharge elbow during operation → Check that the gas discharge hole of the pump is not blocked, and reduce the length of the discharge pipe inserted into the discharge elbow
d) The discharge pipe is too long or excessively bent → Increase the discharge pipe size (up to 44 mm), change the pipeline system and reduce bends
e) The pump body leaks → Replace the lifting unit

6. There is noise but the waste has been cleared
a) A solid obstruction strikes the impeller or the cutter → Remove the obstruction

7. Odour
a) The inlet/outlet pipelines or connections leak → Replace or reseal and reinforce the pipelines
b) The carbon filter is contaminated → Replace the carbon filter
