E-Tronic Solenoids

E-tronic Faucets have been around for many years. Chicago Faucets has updated its components over time. In particular, the most important part of the faucet has been improved: the solenoid. Because of these updates, there are two different solenoid models, and three different solenoid replacement instructions for faucets bought during certain time periods. We’ve made the chart below to help our customers know which solenoid is the right one for their units, and how to remove and replace it.

Sloan Optima Solenoid Replacement Guide

Almost every single electronic faucet utilizes a few key components for operation: a faucet, a power source, a control module assembly, and a solenoid valve. In this article, we will focus on the latter – Solenoid Valves. More specifically, solenoid valve replacements for Sloan Optima Faucets. You will learn the following: common solenoid problems when to use old style versus new style solenoid valves, how to identify which solenoid you need for your Sloan Optima faucet, and where to find additional Sloan repair parts and troubleshooting resources. 

When do solenoids need to be replaced?

Sloan solenoids should last for years when used correctly. But even with proper usage, solenoids don’t last forever. At some point, faucet solenoids will need to be replaced. 

Common Solenoid Valve Problems:

  • Erratic Valve Noises
  • Partially Closed Valves
  • Valve Will Not Open

A number of things can cause the malfunctions listed above. One of those things is the faucet’s solenoid valve assembly. When a faucet is having issues and the culprit is the solenoid valve, then it is likely that the solenoid will need to be replaced entirely.

Why can solenoid replacement be difficult?

There are over 25 different Sloan Optima faucet models, and a handful of different Sloan faucet solenoids to choose from. For most of these faucets, only one style of solenoid works. For others, there are two choices. The variety of faucet styles and solenoids from Sloan can make finding the right Sloan solenoid replacement tricky, especially if you are ordering solenoids for a variety of Sloan faucets.

Old Style versus New Style Sloan Solenoids

It is important to understand that for some faucets, Sloan may have an Old Style Solenoid and a New Style Solenoid. This is important because Old and New Style Solenoids are NOT interchangeable. In other words, if you have an old style solenoid, then you cannot upgrade to the New Style Solenoid when you need to replace the solenoid. Sloan still makes Old Style Solenoids in addition to their New Style Solenoids. There are still many old style faucets in use that will eventually need their old style solenoids replaced. And of course, newer style faucets will eventually need new style solenoid replacements too.

*Old versus New Solenoid Identification Help:

Let’s examine the Sloan EBV-650 solenoid valve because it lists two solenoids in the chart above: the new style ETF-740-A and the old style EBF-1011-A. In order to determine which solenoid your EBF-650 faucet needs, take a look at the solenoid you are removing from the unit, and see if it looks like the Old Style Solenoid shown at the very top of the chart, or the New Style Solenoid, shown in the second row. Luckily, the solenoids look nothing alike, making comparative identification easier if you still have the existing solenoid. 

When you do not have the broken solenoid that needs to be replaced, and the faucet you have can utilize more than one solenoid replacement, then you should give us a call for help. We can help you figure out the model and age of your faucet in order to identify which solenoid you need.

Sloan BASYS Faucet Solenoid Replacement Chart

Faucet solenoids are one of the most commonly replaced faucet parts. Their role within a faucet is critical. In this article, find out what solenoids do, then learn exactly which solenoid is needed for your Sloan BASYS faucet model by using the chart in this article.

Solenoids: What do they do within a faucet?

Faucet solenoids control the flow of water from the inlet to the faucet spout. They convert electronic energy into mechanical energy, enabling electronic faucets to function mechanically through their sensor or manual activation. Solenoid valves are most often made of stainless steel, Teflon, and brass materials. 

For Sloan BASYS faucets, use the Solenoid Replacement Chart below to find the correct solenoid to service your Sloan BASYS faucet. The chart lists several factors that will help you figure out which solenoid is needed for your BASYS faucet. Faucet solenoids control the flow of water from the inlet to the faucet spout. They convert electronic energy into mechanical energy, enabling electronic faucets to function mechanically through their sensor or manual activation. Solenoid valves are most often made of stainless steel, Teflon, and brass materials.

Faucet Height

An easy visual which helps narrow down which solenoid you need for your model BASYS faucet is the faucet’s height. BASYS faucets come in Low, Mid, High and wall mounting heights.

Faucet Model

The model of your faucet will also help you determine which solenoid it uses. Simply find the model number on your faucet, and look for it in the chart below.

Solenoid Options

There are two solenoid models for each Low, Mid, and High BASYS faucet styles. They are color coded according to which gallon per minute (GPM) flow rate they are designed for. Green solenoids are for 0.5 GPM and blue solenoids are for 1.5 GPM. For wall mounted BASYS faucets, the only option is the EXF1012A Solenoid, which has a flow rate of 1.5 GPM. 

*Note: The flow rate of the solenoid must match the flow rate of the BASYS faucet aerator to function properly. So, for example, if you want your Low BASYS faucet model EFX300 to have a low flow rate of 0.5 GPM, then you need to install a 0.5 GPM aerator and the 0.5 GPM solenoid, which is Sloan model EFX37A (Equiparts Part #84103). 

If you are unsure of the aerator flow rate in your faucet, and do not have an old solenoid to reference for color, than you may need to replace both the solenoid and the aerator to ensure that you install parts with matching flow rates.
