## Long description

BWT PROTECTOR BW 3/4" with manual backwash (model 810422) is a mechanical water filter designed for inline installation on 3/4" pipe connections. The unit provides particle and sediment filtration to protect plumbing, appliances and fixtures from dirt, rust and other suspended solids. Manual backwash lets you flush out accumulated debris through a simple valve action without disassembling the housing, maintaining flow and reducing maintenance time.
Advantages
The filter combines a compact design with a durable filter element engineered for repeated manual rinsing. Its manual backwash mechanism enables on-site cleaning of the filter element, extending service intervals and avoiding frequent replacements. The device is suitable for installation in horizontal or vertical pipe runs, offering consistent pressure drop characteristics and straightforward access for routine inspection and maintenance.
Suitable for
Pre-filtration for household water supplies
Protection of washing machines, dishwashers and boilers
Light commercial plumbing and utility lines
Well and mains water systems with particulate contamination
Key specifications
Connection size: 3/4" threaded inlet and outlet compatible with standard plumbing fittings
Filtration type: mechanical sediment/particle separation
Maintenance: manual backwash function to flush trapped debris
Body material: corrosion-resistant housing suitable for potable water systems
Installation orientation: suitable for horizontal or vertical pipe installation

How to use
Install the BWT PROTECTOR BW 3/4" in the supply line using matching 3/4" fittings, ensuring correct flow direction through the housing. After installation, open the supply and check for leaks. When flow is reduced or after a period of service, operate the manual backwash valve according to the included markings: close downstream isolation if present, open the backwash valve to flush water through the element and carry away sediment, then return the valve to the normal position. Follow local plumbing codes and shut off the supply before performing any maintenance.
Usage recommendations
Perform visual inspections regularly and backwash the filter when you notice reduced flow or visible accumulation of debris in the transparent section (if present). Use compatible fittings and replace worn seals or gaskets to maintain leak-free operation. For installations with very high sediment loads, consider a coarser pre-filter or more frequent backwashing to prolong the life of the filter element.
