Mixing Valves for Showers - Moen's Secret to Temperature Control

Have you ever been enjoying a nice relaxing shower only to be suddenly blasted with scalding hot or freezing cold water? It ruins the whole experience and can even be dangerous. Sudden temperature fluctuations are caused by changes in water pressure, and the best way to prevent them is with a quality mixing valve.

That's where Moen comes in. As one of the leading brands for shower systems, Moen mixing valves are specially designed to maintain a steady, comfortable water temperature. In this post, we'll explore the technology behind Moen's legendary temperature control and show you how to choose the perfect valve for your home.

Different Types of Shower Mixing Valves

First, let's discuss the different types of shower valves available. The two main categories are single-handle and multi-handle designs.

Single-Handle vs. Multi-Handle

Single-handle mixing valves allow you to control both water flow and temperature with one lever. They provide a clean, minimalist look. Multi-handle valves use separate handles for hot and cold water to blend them to the desired temperature.

Multi-handle valves provide more precise control, while single-handle models are simpler to operate. Moen offers both styles to suit your shower's look and function.

Pressure Balance vs. Thermostatic Valves

Within each handle style, there are two types of internal valve mechanisms - pressure balance and thermostatic.

Pressure balance valves automatically adjust the hot and cold water flow to compensate for fluctuations in water pressure. This prevents sudden temperature spikes.

Thermostatic valves use a wax element to maintain the set temperature. If the water gets too hot, the wax expands to reduce hot water flow. They provide accurate temperature control within a couple degrees.

Moen uses pressure balancing technology in most of its mixer valves to prevent scalding and ensure reliable performance.

Cartridge vs. Ceramic Disc vs. Ball Valves

The internal cartridge is another factor differentiating shower mixer valves. The three main types are:

• Cartridge - Most common, uses rubber seals/springs
• Ceramic disc - Extremely durable, uses ceramic discs to control water
• Ball valve - Rotating ball component to mix water

Cartridge valves are the most affordable and easiest to repair. Ceramic disc valves last longer, while ball valves operate smoothly but tend to leak over time.

How to Install a Moen Mixing Valve

Once you've selected the ideal Moen mixing valve, it's time for installation. Here's an overview of the process:

Prep the Area

Turn off main water supply and drain pipes. Remove existing hardware. Ensure you have necessary tools - wrench, plumber's putty, thread tape, etc.

Remove Old Valve

Unscrew the clips or nuts holding the valve in place. Gently pull out the old valve and clean mounting area thoroughly.

Secure New Valve

Position new Moen valve and use provided hardware to securely fasten it. Attach supply lines to hot and cold inlets.

Connect Supply Lines

Attach supply lines to valve outlet. Use thread tape or sealant on threads to prevent leaks. Make sure valve is properly aligned.

Check for Leaks

Turn on water and inspect all connections for leaks. Tighten as needed then test temperature/pressure balance.

Install Trim

Add handle kit, escutcheon, etc. to complete the look and cover valve parts.

With good preparation and by following Moen's instructions, installing your new valve should go smoothly. Make sure to test thoroughly before finishing the wall surface.

Troubleshooting Moen Mixing Valves

Moen valves are incredibly reliable, but issues can occur over time. Here's how to troubleshoot common problems:

Leaks

If you have a leaky mixing valve, tighten connections or replace worn out o-rings or seals. Disassemble to inspect internal cartridge.

Temperature Regulation

For problems maintaining stable temperature, clean valve internals, replace seals or cartridge if needed. Adjust balance spool for pressure issues.

Low Pressure

Make sure water supply valves are fully open. Clean/replace filters, showerhead, or cartridge. Switch to a higher flow cartridge.

Noisy Operation

Lubricate o-rings with non-petroleum grease. Flush to remove debris. Tighten connections. Replace worn parts causing rattling.

Volume Control Problems

Ensure correct cartridge model with flow control. Clean/replace flow control component. Check for obstructions restricting water flow.
