Homeowner's Guide & Tool Kit for Shower Temperature Limiter Adjustment
Product Opportunity: Shower Temperature Adjustment Kit & Guide
Analysis: The Reddit user's struggle with adjusting their shower's hot water temperature, even after accessing the valve, is a common headache for many homeowners. The conflicting advice in the comments—whether to adjust at the water heater or the valve itself—shows just how confusing this can be. This points to a real need for a targeted solution.
Product Suggestion: A "DIY ShowerMax Temp Adjuster Kit" comprising:
-
Comprehensive Multi-Brand Guide:
- Format: A durable, water-resistant, spiral-bound physical booklet and/or a QR code linking to a dedicated online resource with clear, concise video tutorials and high-resolution diagrams.
- Content: Step-by-step instructions for identifying and adjusting temperature limit stops/rings on common shower valve brands (e.g., Delta, Moen, Kohler, Pfister, Grohe). It should cover various mechanism types (e.g., rotational limit stops, pull-and-turn rings). Crucially, it must include safety warnings about testing water temperature post-adjustment to prevent scalding and advice on when not to proceed (e.g., if the valve is seized or damaged, requiring a plumber).
-
Curated Toolkit:
- A selection of essential, often small, tools required for the task, which users might not readily have or know they need. This could include:
- A set of common Allen keys (hex keys) in metric and imperial.
- Small Phillips head and flat-head screwdrivers (stubby or precision types).
- A non-marring plastic pry tool or spudger for removing decorative caps.
- Potentially a specialized, thin spanner or custom tool if a particular widely-used valve type requires it (e.g., for some retainer nuts or specific adjustment rings).
- (Optional add-on) A basic, inexpensive digital water thermometer for accurate temperature testing.
- A selection of essential, often small, tools required for the task, which users might not readily have or know they need. This could include:
Expected Benefits & Revenue:
- Empowers Users & Solves a Real Problem: Directly addresses the user's struggle, enabling homeowners to safely perform a common maintenance task, improving shower comfort and preventing frustration.
- Saves Costs: Offers a significantly cheaper alternative to calling a plumber for what is often a simple adjustment.
- Reduces Confusion & Increases Safety: Provides clear, reliable instructions, mitigating the risk of incorrect adjustments that could lead to scalding or insufficient hot water. The guide would emphasize safe temperature ranges (e.g., around 120°F/49°C max at the tap).
- Revenue Generation:
- Sales of the physical kit (Guide + Tools): Estimated retail price of $24.99 - $39.99.
- Sales of the guide alone (digital or physical): Estimated price of $9.99 - $14.99.
- Potential for affiliate revenue if recommending specific replacement cartridges or more advanced tools not included in the basic kit.
- The target market includes DIY homeowners, new homeowners, and potentially landlords. Marketing could be done through DIY blogs, home improvement forums, and targeted online ads. Given the commonality of the issue, sales volume could be substantial.

Trying to increase max hot temp in my shower. I've taken off the handle but the valve underneath won't budge. Any tips?

As it says in the title. I've unscrewed the handle to access the valve underneath. I've tried using the red bit to turn it clockwise and counterclockwise but it's not moving an inch. I've als

What the... Are we looking at there? Lol
About the only thing you can do is turn up the temperature on your hot water heater, but be careful you can get seriously burned if you turn it up t

Turn up the temperature on your water heater, then run the kitchen tap for awhile, and temp it with a thermometer. Don’t go over 106F.
u/MadDadROX
How high?
u/Mdrim13
125-140 normally. Mine is 145F.
u/Dangerous_Grab_1809
Why would you think this is the place to adjust it? Change the temp at the heater. If you can see the pipes, are they insulated? Even if you can only insulate near the hot water heater, it
u/D1kCh33z
Well, time to put it back together and go turn up your water heater.
u/SnooKiwis6943
Other comments say it is at the waterheater. This is only true if all your fixtures have a hot water temp that is the same. If this valve is the only valve with issues, it’s a valve issue.
u/2ndChanceCharlie
Yeah the red thingy just needs to be taken out and rotated.
u/Mdrim13
That’s really low.

u/SpiffyPool
Its at your water heater to adjust hot water temp.
u/noachy
And dangerous if you have a tank based water heater
u/Either-Gur-7679
In certain heads, for example - Pfister, there’s a notch to adjust the temperature you get from the shower head. The water heater is the ultimate source but the notch on the handle determines
u/lotusgardener
So that red thing is the adjustment on the mixing valve. But the way it is installed, it looks like you are already at the hottest setting. In that case you will have to up it at the water he
u/CaptainTooStoned
Go to your hot water heater and there will be a little knob for the temperature, go turn it up, don't turn it all the way though or you will have the water coming out scalding hot.

Apparently the majority of responses here don't know that many cartridges have a temp limiter adjustment. Anyhoo, I've only worked with Delta, and the collar simple pulls out slightly and twi
