Connection 3/4" to 1/2" Forged Brass body Review: Mauvais article ! - Ne fonctionne pas. Raccords achetés pour pouvoir installer l'article. Hop.... Encore un achat effectué par erreur. Confier le sort d'une pompe hydraulique à un système à 14€ relève de l'erreur de reflexion !!!!!!!!! Review: No tiene nada que ver con presión, sino flujo - No es así - "Cuando se abre el grifo, la presión disminuye, el interruptor se encenderá, después de cerrar el grifo la presión alcanzará un cierto nivel que se apagará." Porque no es un presostato. Es un interruptor que detecta flujo de agua. Enciende cuando hay flujo, apaga cuando no. Nada que ver con presión. ## Features - Electronic Pressure on/off Switch, Adjustable - Fits Merry Tools shower pumps and other similar pumps - Forged Brass body, 3/4" - 1/2" Connections - Adjustable pressure level ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WK221H2 | | Best Sellers Rank | 71,409 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 225 in Pressure & Vacuum Measurement | | Brand | Merry Tools | | Colour | Gold | | Country of Origin | China | | Customer Reviews | 3.4 out of 5 stars 6 Reviews | | Item Type Name | Automatic Water Pump Pressure Control Switch | | Item Weight | 0.14 Kilograms | | Item weight | 0.14 Kilograms | | Manufacturer | Aim Tools | | Material | Brass | | Model Number | SP15141002A | | Part Number | localization-B07WK221H2 | | Power source | Corded Electric | | Product Style | Submersible | | Style | Submersible | | Unit Count | 1.0 count | | Usage | Bathroom, Showering | ## Product Details - **Brand:** Merry Tools - **Item weight:** 0.14 Kilograms - **Manufacturer:** Aim Tools - **Material:** Brass - **Power source:** Corded Electric - **Style:** Submersible - **Voltage:** 220 Volts (AC) ## Images ![KATSU Automatic Water Pump Pressure Control Switch 220V Adjustable Electronic Pressure Controller Fits Merry Tools Shower Pumps and Other Similar Pumps SP15141002A - Image 1](https://m.media-amazon.com/images/I/61CDRUB1vgL.jpg) ![KATSU Automatic Water Pump Pressure Control Switch 220V Adjustable Electronic Pressure Controller Fits Merry Tools Shower Pumps and Other Similar Pumps SP15141002A - Image 2](https://m.media-amazon.com/images/I/61PkqtN5LPL.jpg) ![KATSU Automatic Water Pump Pressure Control Switch 220V Adjustable Electronic Pressure Controller Fits Merry Tools Shower Pumps and Other Similar Pumps SP15141002A - Image 3](https://m.media-amazon.com/images/I/61-wH+lqmZL.jpg) ![KATSU Automatic Water Pump Pressure Control Switch 220V Adjustable Electronic Pressure Controller Fits Merry Tools Shower Pumps and Other Similar Pumps SP15141002A - Image 4](https://m.media-amazon.com/images/I/61e3AzgeMPL.jpg) ## Customer Reviews ### ⭐ Mauvais article ! *by M***E on 28 August 2025* Ne fonctionne pas.
