Riser PipeThe Budget Series of Crystal Sand Vessels (Manual) uses the Runxin F56A1 Manual Purification Valve head. Which needs to be manually set to go from Normal Operation (Filtering), to Backwash cycle, then Fast Rinse.
Filtershop also has several other Crystal Sand Glass Media Vessel series available:
Crystal Sand Filter Vessel Normal Operation, Backwashing & Fast Rinse



What size Crystal Sand Media Vessel should I get?
The Budget Series Crystal Sand Media Vessels come in 4 sizes:
- 25 Litre Budget Series Crystal Sand Media Vessel - Manual (Maximum Flow rate: +/- 1000LPH @ Maximum Turbidity of 2 NTU*)
- 50 Litre Budget Series Crystal Sand Media Vessel - Manual (Maximum Flow rate: +/- 1500LPH @ Maximum Turbidity of 2 NTU*)
- 75 Litre Budget Series Crystal Sand Media Vessel - Manual (Maximum Flow rate: +/- 2000LPH @ Maximum Turbidity of 2 NTU*)
- 100 Litre Budget Series Crystal Sand Media Vessel - Manual (Maximum Flow rate: +/- 2500LPH @ Maximum Turbidity of 2 NTU*)
Not sure which size Crystal Sand Vessel to get for your water and application? Contact Filtershop, and we will be happy to guide you on the best size unit for your application.
*While the crystal sand vessels do have a liter per hour flow rating, this is only meant as a guide and is based on the turbidity level being equal to or less than 2 NTU. In situations where the turbidity level is far higher, the flow rate capacity of these units will be far less.
**Keep in mind that the "deeper" (more volume) a crystal sand vessel, the more effective the removal of sediment will be, and the less likely that some sediment will "bypass" through the media and not be captured by the media.

Warranty*:
The Budget Series Crystal Sand Media Vessels come with a 1-year* Warranty. Please note that the warranty does not cover the filtration media, as its life span is completely dependent on the quality of the source water and how regularly the backwash cycle has been run.
*Please note that the warranty does not cover damage caused by mishandling, improper installation, or in situations where the max operating parameters for the product are exceeded.
**Please note that with any FRP Vessel-based water filter systems. It is highly recommended that a Vacuum breaker valve be installed after the vessel. To help protect the vessel from damage due to any pressure differential across the vessel. Failure to install a vacuum breaker valve after a FRP Vessel will void the vessel's warranty.
***The Filtration Vessels Components are rated for a maximum pressure of 6 bar (90psi). If your source water has higher pressure or is prone to "water hammering" ( pressure spikes), it is strongly recommended that a pressure regulator/reducer be installed before the system. Failure to do so will void any warranty on the components for any damage caused by water pressure.
Additional Options: Pressure Gauges, Flow Meter (Rotameter), and By-pass piping Combination Options
There are a number of different fittings and additions that can be added to the Filttration Vessel System, including a By-pass, Inlet and outlet Pressure Gauges, as well as a 250-2500LPH Flowmeter (Rotatmeter).
These additions can be added separately or in a number of combinations with one another. Please see below for information on the different fitting options.

*Please note that the picture above is just to illustrate an example of the pipe work used for a fitting combination setup. Depending on the system type and the fitting options selected, the pipework on your system will likely appear different.
**Please note that these additional fitting combinations are built to order, and construction time is 2 to 3 working days from when payment has been received.
By-Pass Piping
Adding a bypass to the system allows you to divert the flow of water around the system if you need to conduct maintenance on the system.
Water Pressure Gauges
The pressure gauge allows you to monitor the pressure of the incoming source water.
This helps you to see if the water pressure coming is high enough for an adequate flow pressure through the vessel (minimum 1 bar for water softeners).
Alternatively, the pressure gauge will indicate if the water pressure is too high for the Vessel and components (maximum of 6 bar). In which case, you should then install a pressure-regulating valve before the filter system.
Flow Meter (Rotameter) 250 to 2500LPH
The Flow Meter (Rotameter) allows you to see how much draw (flow rate) is growing through the filter system at a particular time and helps to give you an idea of how many litres per hour (LPH) you are using at a given time. For Example, flow rate (LPH) in a household when one versus two showers are running.
Additional Options:
Runxin Brass Reducing Valve with Pressure Gauge
The Runxin PRV is designed to automatically reduce a higher inlet pressure to a steady lower downstream pressure, regardless of fluctuations in flow rate or inlet pressure. This ensures that downstream components receive water at a consistent pressure, enhancing system efficiency and longevity.
Constructed with high-quality materials, the valve offers durability and resistance to corrosion, making it suitable for long-term use in various environments. Its compact design allows for easy integration into existing systems without requiring significant modifications.
The valve operates effectively within a pressure range of 2 to 6 bar (0.2 to 0.6 MPa) and a temperature range of 5°C to 50°C, accommodating a wide array of water treatment applications. Whether used in reverse osmosis (RO) systems, filtration setups, or general water supply networks, the Runxin PRV delivers reliable performance.

PVC Threaded and Glue Fittings
PVC(Polyvinyl chloride) fittings are used to connect sections of pipes or tubes, adapt to different sizes or shapes, and controlling the flow of water. There are two predominant types of PVC fittings, namely PVC Glue Fittings and PVC Threaded Fittings. The difference between the two is that PVC Glue Fittings result in permanent joints and PVC Threaded Fittings are semi-permanent and can be replaced. PVC Glue fittings are joined with primer and cement- a chemical solvent that melts the surface of the PVC and then quickly re-hardens to fuse the pieces together. This results in an airtight, leak-proof bond similar to what you get with welding metal. An example of such a fitting is a PVC Glue Reducing Socket which is used to join together two pieces of PVC pipes with different diameters. Another example would be a 90 Degree Elbow which is used to connect two pipes of the same diameter at an angle of 90 degrees.PVC Threaded fittings utilise a simple threaded connection whereby replaceable 'male threaded' are screwed into 'female threaded'.Male threads have a thread on the outside of the fitting and female threads have a thread on the inside. When you thread the fitting in, it compresses against the other threads.PTFE tape is used to thread these together and the proper way to assemble threaded fittings is to finger-tighten, then add one to two turns but no more. An example of a threaded fitting is a Reducing Nipple Male Threaded which is used to connect between two female threads of different diameters.
