Frequently Asked Questions - BA295 HONEYWELL

What is the purpose of the Honeywell BA295 backflow preventer?

The BA295 is a backflow preventer that protects drinking water networks by preventing back pressure or back siphonage. It divides into three pressure zones and opens a discharge valve when differential pressure falls below 0.14 bar.

What are the recommended installation conditions?

Install the device horizontally with the discharge valve pointing downwards. Ensure good access, protect from frost, and ventilate well. A straight pipe section of at least five times the nominal valve size is required after the backflow preventer.

How do I test the discharge valve?

Use a test control unit like TK295 or TKA295. For a quick test, lower the inlet pressure: if the discharge valve opens (drops), it functions correctly. Detailed procedure is in the test unit instructions.

How often should maintenance be performed?

Inspection is recommended every 6 months, and maintenance every 1-3 years, depending on local operating conditions. Always use authorized personnel.

Can I clean the cartridge insert myself?

Yes, the operator can clean the cartridge insert. Do not use cleaning agents with solvents or alcohol. Close shut-off valves, release pressure, remove cover, clean or replace the cartridge and lip seal, then reassemble.

What should I do if the discharge valve opens without reason?

Possible causes include pressure strokes or fluctuating inlet pressure. Install a pressure reducing valve (e.g., D06F) upstream. If the cartridge is contaminated, replace it.

What spare parts are available for the BA295?

Spare parts include cartridge insert (part numbers 0903733 for 1/2"-1", 0903745 for 1-1/4"-2"), check valve complete, and lip seals. Refer to the spare parts list in the manual.

What is the maximum operating temperature?

The maximum operating temperature is 65°C.

Do I need a strainer before the backflow preventer?

The BA295 has an integral strainer (0.6 mm mesh). For highly polluted water, install a fine filter (e.g., F76S) upstream to ensure proper function.

How do I dispose of the BA295?

The housing is red bronze, valve cartridge is synthetic, check valves are synthetic or red bronze, and ball valves are brass. Follow local recycling/disposal regulations. Do not let detergents enter the environment.

1. Follow the installation instructions.

The factory-set position of the ball valves may not be altered. Non-compliance with this instruction will make any warranty claims null and void.

1. Use the appliance

according to its intended use
- in good condition
with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the applications detailed in these installation instructions. Any other use will not be considered to comply with requirements and would invalidate the warranty.
4. Please take note that any assembly, commissioning, servicing and adjustment work may only be carried out by authorized persons.
5. Immediately rectify any malfunctions which may influence safety.

2. Functional description

BA type backflow preventers are divided into three pressure zones. The pressure in zone ① is higher than in zone ②, which in turn is higher than in zone ③. A discharge valve is connected to zone ② which opens at the latest when the differential pressure between zones ① and ② falls to 0.14 bar. The water from zone ② discharges to atmosphere. In this way the danger of back pressure or back syphonage into the supply network is prevented. The pipework connection is interrupted and the drinking water network is protected.

7. Assembly

7.1 Installations Guidelines

• Install shutoff valves before and after backflow preventer
  Install in horizontal pipework with the discharge valve downwards
• Ensure good access
• Simplifies maintenance and inspection
• Backflow preventers of this type have an integral strainer which protects the device from the ingress of dirt. With highly polluted water a fine filter should be installed upstream to ensure the correct function of the device.
• Do not install in places where flooding can occur
• The installation environment should be protected against frost and ventilated well
• Install discharge pipework which has adequate capacity

Use and type of installation according to DIN EN 1717

7.2 Assembly instructions

1. Thoroughly flush pipework
2. Install backflow preventer

Install in horizontal pipework with discharge connection directed downwards
Note flow direction (indicated by arrow) o Install without tension or bending stresses
- Provide a straight section of pipework of at least five times the nominal valve size after the backflow preventer

1. Attach drain pipe to discharge connection (plastic pipe HT 50, HT70)
2. The appliance is ready for use

8. Maintenance

We recommend a planned maintenance contract with an installation company

Maintenance of backflow preventer must be carried out by authorized personnel!
