Designed for easy installation with standard threads and reusable backwash cleaning, it ensures long-lasting, crystal-clear water while protecting downstream devices. Ideal for urban water supplies, it pairs perfectly with pressure regulators to maintain stable water pressure and maximize filtration efficiency. ## Description iSpring Innovative backwash filter is the professional first filter stage for any modern domestic water installation. Designed as a backwash filter with pressure regulator compatibility, it reliably protects your downstream devices and fine filters from sediment, limescale and corrosion. With patented Siliphos technology and convenient backwash function, it is the economical and durable solution for crystal clear, protected water in any household Review: Does the job but pressure gauge useless - The pressure gauge leaked, but I removed it and blanked out the hole for it. I use this for filtering rain water coming into the house from a pump in a tank outside and regulated the pressure by observing the flow rate at the rain water tap. With a course and finer basket filters on the rain water pipes to the tank, this is perfect for the final filter before supply to the toilet cisterns, rain water tap and washing machine. Easy to flush and removable filter bowl useful if a more thorough clean is necessary. Only 3 stars because the pressure gauge was useless Review: Fonctionne comme attendu - Facile à mettre en œuvre et robuste. La pression s'adapte bien et rapidement. Parfait. ## Features - 【Precise 50-micron backwash filter】: Our whole-house sediment pre-filter reliably filters rust, sand, dirt, and coarse particles (up to 50 microns) – the ideal first stage before further fine filters or a pressure reducer. Thanks to the backwash filter function, the filter performance remains permanently high - 【Reusable & easily back-flushable】: The filter can be cleaned and reused by simply back-flushing. This protects downstream fine filters, extends their service life, and saves replacement costs. Perfect for multi-stage filter systems - 【Protection against limescale & corrosion with Siliphos】: Integrated Siliphos technology prevents limescale build-up and protects fixtures from corrosion – ideal in combination with a backwash filter with pressure reducer for long-lasting pipes and stable pressure - 【Easy Installation with Standard Threads】: Equipped with G1" (DN25) and G3/4" (DN20) threads for direct, tight compatibility with common German household water lines. Transparent housing for visual control, including drain valve with standard garden hose connection - 【Optimal combination with pressure reducer】: Range of use: 4-38°C, 1.4-7 bar. Designed for indoor use. We recommend combining with a pressure regulator for water to minimize pressure surges and maximize the filtering efficiency of your system ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C6D387XM | | Benefits | Sediment reduction and water pressure regulation | | Best Sellers Rank | 237,988 in DIY & Tools ( See Top 100 in DIY & Tools ) 444 in Replacement Under-Sink Water Filters | | Brand | iSpring | | Brand Name | iSpring | | Customer Reviews | 4.2 out of 5 stars 69 Reviews | | External Testing Certification | NSF | | External testing certification | NSF | | Included Components | Pressure gauge | | Item Dimensions D x W x H | 30D x 20W x 15H centimetres | | Item Type Name | Backwash filter | | Manufacturer | iSpring | | Manufacturer Part Number | 1 | | Material | Brass | | Material Type | Brass | | Model Number | WSP50PRG | | Number of Items | 1 | | Number of Packs | 1 | | Product benefits | Sediment reduction and water pressure regulation | | Product dimensions | 30D x 20W x 15H centimetres | | Set Name | Backwash filter with pressure regulator | | UPC | 810004173491 | | Unit Count | 1.0 count | ## Product Details - **External testing certification:** No - **Item weight:** 454 g - **Material:** Metal - **Product benefits:** Reduces Sediment - **Product dimensions:** 6D x 11W x 66H centimetres ## Images ![iSpring WSP50PRG 1" Sediment Spin Down Water Filter with Pressure Regulator, High Precision Filter for Urban Water Supply, 50 Micron - Image 1](https://m.media-amazon.com/images/I/71a5N697hOL.jpg) ![iSpring WSP50PRG 1" Sediment Spin Down Water Filter with Pressure Regulator, High Precision Filter for Urban Water Supply, 50 Micron - Image 2](https://m.media-amazon.com/images/I/71wiFxATkXL.jpg) ![iSpring WSP50PRG 1" Sediment Spin Down Water Filter with Pressure Regulator, High Precision Filter for Urban Water Supply, 50 Micron - Image 3](https://m.media-amazon.com/images/I/71zRrBDH6rL.jpg) ![iSpring WSP50PRG 1" Sediment Spin Down Water Filter with Pressure Regulator, High Precision Filter for Urban Water Supply, 50 Micron - Image 4](https://m.media-amazon.com/images/I/81WjtGRdnlL.jpg) ![iSpring WSP50PRG 1" Sediment Spin Down Water Filter with Pressure Regulator, High Precision Filter for Urban Water Supply, 50 Micron - Image 5](https://m.media-amazon.com/images/I/71n7ZTn7SFL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Should i expect a water pressure (psi) reduction by using this? if so, what pressure % drop have you experienced?** A: I'm getting a HUGE pressure drop of over 40 PSI! With sprinklers running I'm measuring 85 PSI upstream and 45 immediately downstream of the filter. It drops to 25 PSI after filtering sediment for several days. Back flushing as designed partially restores pressure the first few times, but then the filter element requires removal and scrubbing. Mine is the 50 micron filter element. I am now shopping for a 500 micron (which will probably act like no filter at all on my super-fine sediment.) I have a high flow rate of about 10 GPM in a 3/4" PVC sprinkler pipe fed by canal water (non-culinary) - a very demanding situation likely to produce a high pressure drop. Still, this big drop is far too much to be acceptable. I would not recommend this filter unless you have a much slower flow rate. **Q: is the clear housing glass or plastic** A: High impact plastic, bpa free and weather proof. **Q: Is the brass lead free? Can you provide certification to prove it?** A: John Browning, the seller should be monitoring these questions as much, if not more so, than the general public. **Q: Is the plastic part bpa free? what kind of plastic is it?** A: Hi, The plastic portion of this unit is made from PCTG and it is BPA free.
