Spare parts and accessories
The most frequently worn and lost parts of radiator flushing machines are hoses, filters, and valves. This category includes basket filters that keep the machine running efficiently, swivel-head radiator connection hoses, drain hoses, and 4-way backflush valves that reverse the flow direction in bidirectional machines. A laser thermometer for measuring temperature differences across the system can also be used to check results before and after radiator flushing.
Functions of the parts
- Basket filter: Catches sediment returning from the system to protect the pump; may be compatible with many machine models.
- Connection hose: Connects the machine to the combi boiler or radiator connection; swivel-head unions make connection easier.
- Drain hose: Allows dirty water to be safely discharged to a drain.
- Backflush valve: Reverses the flow direction for bidirectional flushing.
- Laser thermometer: Measures the temperature at different points on radiators without contact, revealing blocked areas.
Selecting the right part
When purchasing spare parts, check the brand, model, and connection dimensions of your machine. Hose length should be selected according to the access distance to the system; a hose that is too long can cause flow loss. The pressure and temperature rating of valves and unions must be compatible with your machine's operating values.
Maintenance recommendations
After each flushing job, empty and rinse the basket filter. Store hoses without kinking or crushing them; replace hoses that have cracked or hardened. When union gaskets start leaking, replace them with new ones.
Frequently asked questions
How is a laser thermometer used in radiator flushing?
By measuring the temperature difference between the upper and lower sections of a radiator, heavily sedimented radiators can be identified; the same measurement after flushing allows the result to be compared.
Does the basket filter fit every machine?
Even for filters stated to be compatible with many models, the dimensions should still be compared.
What does a backflush valve do?
It reverses the flow direction so that sediment is dislodged from both sides.
What should I do if a hose connection leaks?
Check the gasket and reconnect without over-tightening the union; if the problem persists, replace the gasket.
Where can I find machine models?
Browse the radiator flushing machines category for new machines.
What length should the hose be?
It is determined by the distance between the machine's position and the combi boiler or radiator connection; shorter hoses reduce flow loss, while a hose that is too short makes it difficult to position the machine. Options such as 2.5 and 3 meters are available in the category.
