## Overview

The iSpring WSP-50 is a reusable whole house spin down sediment filter featuring a 50 micron stainless steel mesh that effectively removes sediment, rust, and large particles. Designed with a durable lead-free brass head and clear housing, it offers easy visual monitoring and maintenance through simple flushing. Compatible with 1" MNPT and 3/4" FNPT fittings, it supports up to 20 GPM flow rate and operates efficiently within 40-100°F and 20-90 psi, making it an essential frontline defense for your home's plumbing system.

## Description

The WSP-50 spin down sediment filter is ideal for filtering out course sediment larger than 50 micron. The stainless steel screen makes the flushing and cleaning process very simple, allowing flushing of the contaminants through the bottom of the filter when the cartridge begins to get clogged. This allows the stainless steel filter cartridge to be used over and over again without needing to be replaced. The 1 inch outlet MNPT fitting provides a maximum 20 gpm flow rate, and the WSP-50 also features 3/4 inch NPT threads on the inlet and outlet. Specifications: Mesh pore rating: 50 micron Dry weight: 1 lb. Dimensions: 3. 5" width x 9" height Suitable temperature range: 40 - 100 °F Suitable pressure range: 20 - 90 psi

Review: Just what was needed - Using this on a rainwater collection system between the tanks and the RV 12v pump. Works wonderful, no issues and is nice and easy to clean when sediments build up. The valve is nice but it is also real easy to unscrew the shroud and clean the stainless screen itself.
Review: bonne qualité - Produit de bonne facture. Il a l'air très solide, et est livré avec un joint de rechange et un support. Le seul problème est les raccords utilisés qui sont coniques, et nécessites des adaptateurs pour être reliés à des raccords européens (NTP to BSP). J'ai contacté le SAV qui a été très réactif. ils m'ont envoyé un filtre de rechange en guise de dédommagement, car ils ne disposent pas dans leurs catalogues d'adaptateurs. Je remercie Francis du SAV qui a été très réactif.

## 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. For more details, please contact us at (678)261-7611
