What is the Difference Between Moen 2510 and 2520 Shower Valve

What sets these units apart from each other? Below is a brief description to show Moen 2510 vs 2520 shower valve comparison to help you choose wisely.


The biggest hassle with installing 2520 is that the manual guide is vague. So, unless you are an expert at installing shower valves, we ask you to refrain from doing it yourself. 

We did not find such difficulties with the 2510 installation process, but again the problematic instruction guide was in the way of precise positioning of setting up the unit. 

Most have remarked upon the 2510 unit’s straightforward design to understand the fitting navigation promptly. That means even a novice can follow up with the procedure to continue installation without any slip-up. 

Connection Type

This is where the real difference can be distinguished. It is because the 2510 model has ½-inch male connections in a threaded format. As a result, the connection should be tightened to a certain degree to avoid substantial pressure. 

You will have to seal the thread with tape before moving to the next procedure. This will prevent the valve from leaking water when in use with full force. 

The 2520 unit model, on the other hand, comes in ½-inch sweat-to-sweat connections. Thus, you are going to need a soldering kit. 

It means you should be able to obtain specific tools like appropriate solder for copper plumbing, a torch to melt the solder, flux to make the solder flow correctly, and fitting brush to prime the insides of the copper fittings. 

So, 2520 might require more attention than 2510. In any case, they both serve impressively despite the distinction of assembling type. 


While both models are forged with brass for solid durability, some slight changes were discovered after/during installing. 

For instance, 2510 has a bulky design compared to 2520, which should be taken under consideration before fitting. The rotating lever function works great on both parts but more effective on the 2520 model. 

2520 does not have male threaded ends, while the latter model does. Even though it is mentioned that both are compatible with shower and tub use, unit 2520 seems well-suited for the purpose rather than the 2510 shower valve. 

2510 can be applied in the kitchen plumbing, too, making it more versatile. However, it is better to mount 2520 in the bathroom only. 

Aside from these differences, the consistency of water temperature and both models’ flow remain the same.

Q: What does Moen PosiTemp mean?

Ans: It is a temperature-sensitive design that averts getting scalded or unforeseen ice-cold water blast when taking a shower. The system is an important feature to protect adults and children from getting injured or shocks.

Q: How do I know if the Moen cartridge is bad?

Ans: If you experience leakage from different areas even after turning off, then it must be checked. Other symptoms include the inability to receive too hot or too cold water, difficulty turning, opening, closing the shower valve, etc.

Q: How long does a Moen cartridge last?

Ans: It will last about 20 to 30 years at most, which is a great deal considering its steep price.

Q: Can I control the volume and temperature of either unit?

Ans: Moen 2510 and 2520 have only one handle to control the water temperature; a simple lever rotation will do the trick. These valves, nevertheless, lack volume control.

Q: Are all Moen shower valves the same?

Ans: No. The brand has manufactured three kinds of valves so far. They are known as Standard, PosiTemp, and Moentrol. All of them might look quite similar, but the trim is not interchangeable.


It is an understandable situation where one can easily feel frustrated with almost identical two units. However, our article has pointed out that Moen 2510 vs 2520 comparison is possible. 

Hopefully, things will look up much clearer this way to select the right unit for your benefit.
