From pause to shutoff
What does “pause” mean on a hand shower?
On the products we checked, pause is a flow reduction. Delta and Moen both describe their pause controls as reducing the water to a trickle, and Delta adds that the user’s temperature setting is kept. On these products a trickle during pause is the designed behavior, not a fault.
Water Pik’s XQP-633 manual says its pause lever will not shut off the water completely, because a small continuous flow is needed to meet plumbing code requirements. The manual names no code.
A trickle is not a law of physics. A Water Pik patent describes one design with trickle openings and another where the valve seals fully. What a product does is therefore a question for its data sheet.
| Term | What it means |
|---|---|
| Pause or trickle | Reduces flow at the hand shower while the valve stays open. |
| Shutoff | Stops the water; the system’s instructions name the control that does it. |
| Diverter | Sends water to one outlet or another. |
| Volume control | Sets how much water flows through the valve. |
| Temperature control | Sets the mix of hot and cold at the valve. |
Why does a paused hand shower still trickle?
The makers give two reasons, both for their own designs. Water Pik points to code requirements, without citing them. Its patent adds that trickle openings, sized for the water pressure, relieve pressure in the handle when the pause stays closed for long periods. In sequence:
- The shower valve is open and mixing hot and cold.
- Water flows through the hose to the hand shower.
- The user presses or turns the pause control.
- The control closes most of the flow path.
- A small flow continues through trickle openings.
- Releasing the pause restores full flow at the same valve setting.
Water Pik states that its trickle setting restricts flow to roughly ½ to 1 gallon per minute. That figure is Water Pik’s own; other products will differ.
Which parts sit between the valve and the hand shower?
The pause is only one part of the shower system. Knowing where each function sits shows where the water can actually be stopped.
| Part | Role |
|---|---|
| Shower valve and cartridge | Opens, mixes and shuts off the water. |
| Diverter | Routes water between outlets; Delta’s R11000 rough is a three-port diverter used alongside a mixing valve. |
| Backflow protection | Kohler lists air gap, two check valves or a vacuum breaker as options for hand-held showers. |
| Hose | Connects the outlet to the hand shower. |
| Hand shower | The spray head, with its spray modes and any pause control. |
| Pause control | Reduces flow at the head, by button, lever or dial. |
Moen’s DN8001 instructions require a certified backflow preventer at the hose inlet where local code demands it, and its T8346 specification cites ASME A112.18.3 for backflow. A pause control is not backflow protection.
Pause, diverter, volume or valve: which one stops the water?
Each control does something different to the flow. The table uses the makers’ descriptions; where a source is silent, the cell says so.
| Control | What the sources say | Stops the water? |
|---|---|---|
| Pause at the hand shower | Delta and Moen: reduces flow to a trickle. | No, on the products checked. |
| Diverter | A Delta representative: its 3-way arm diverter is not a complete shutoff; do not cap an outlet. | No. |
| Volume handle | Delta’s T17288 trim adjusts volume with the handle and temperature with a dial. | The page does not say. |
| Shower valve | Opens and closes the supply to the shower outlets. | That is its function; confirm the off position on the valve’s data sheet. |
Delta’s advice not to cap an outlet shows that a diverter holds pressure behind it. None of these controls is a service shutoff for repairs.
How is a pause operated on different products?
The same function comes in several forms. The examples below are named products; availability varies by market.
Lever on the head
Water Pik’s XQP-633 has a lever under the head, pushed away to reduce flow and pulled back to restore it, in any spray setting. Delta’s 59426-PK uses a lever rotated around the face of the head.
Position on a spray dial
On Delta’s 75740BL, pause is one of the positions on the spray dial.
Button
Moen’s T8346 and Speakman’s commercial hand shower list a pause button or pause control.
Temperature-triggered trickle
Moen’s 230H2EP reduces flow to a trickle automatically once the water reaches 95 °F.
Cradle-activated
A Kohler patent describes a cradle that reduces flow when the hand shower is docked. That is a patent, not evidence of a product on sale.
- Where the pause control sits
- Whether it is manual or automatic
- Whether it works in every spray mode
- The trickle flow the maker states, if any
What controls temperature while the shower is paused?
Pause keeps the valve setting, so temperature stays a valve question. A retained setting is not a guarantee of a safe restart temperature; that depends on the valve and the supply. Four points from valve makers and ASSE apply.
Pressure-balance and thermostatic valves
Delta says its TempAssure thermostatic valves measure and control temperature, while its Monitor pressure-balance valves balance pressure. Moen states its T8346 holds temperature to ±3.6 °F.
Shower valve standard
ASSE’s white paper describes ASSE 1016 valves as pressure-balancing, thermostatic or combination types that protect against scalding and thermal shock, with limit stops set at installation.
Minimum flow
The same paper says showerhead flow must not fall below the valve maker’s published minimum. It discusses devices that cut flow to a trickle when the water gets too hot, but not a user-operated pause, so check the valve maker’s minimum when a pause or low-flow head is specified.
Maximum outlet temperature
Hansgrohe’s North American instructions set the valve’s maximum at 120 °F (49 °C), or 112 °F (44 °C) in Massachusetts.
Hansgrohe also lists crossflow, where hot water is forced into the cold line, as a fault of dirty or leaking check valves in its thermostatic mixer. No source links crossflow or scalding to pause buttons, so this page does not claim a connection.
What do flow standards and labels cover?
Buyers see flow ratings and standards on hand-shower data sheets. None of the sources below sets rules for pause or trickle modes.
| Standard or label | What it covers |
|---|---|
| ASME A112.18.1/CSA B125.1 | Supply fittings including showerheads and hand-held showers, per the CSA summary. |
| Exclusions of that standard | Temperature-actuated in-line mixing valves (CSA B125.3 or other standards) and flexible water connectors under continuous pressure (ASME A112.18.6/CSA B125.6) are covered elsewhere, per ANSI’s summary. |
| EPA WaterSense showerhead specification | Hand-held showers rated at 2.0 gpm or less, with minimum flows of 60% at 20 psi and 75% at 45 and 80 psi. |
| EPA’s comparison | Standard showerheads use 2.5 gpm; WaterSense-labeled ones no more than 2.0 gpm. |
| Delta 59426-PK | Rated 1.75 gpm at 80 psi, WaterSense labeled, with a restrictor that must not be removed. |
How should a buyer specify pause and shutoff?
These steps apply the facts above to a hotel or project order. They are procurement guidance, not installation instructions.
- Name the hand shower. Record the model, because pause behavior is product-specific.
- State what pause does. Write “reduces to a trickle” or the maker’s own description, not “stops the water”.
- Locate the shutoff. Identify the control that actually stops the water, and any service stops.
- Check the valve. Confirm the valve type, its limit stop and its minimum flow.
- Confirm backflow protection. Name the device and the standard it meets.
- Record the flow rating. Note the rated flow and any label claimed for the model.
- Brief the operator. Tell housekeeping that a paused shower is still running.
When guests expect a full stop
If the brief calls for a hand shower that stops completely, ask whether the maker offers such a design and what it states about codes. Water Pik’s patent shows a fully sealing design is possible, but the products checked here trickle.

What should you send and ask before a quotation?
A complete request separates the pause from the shutoff and the valve. Each question maps to a point earlier in this guide.
| Question | Why it matters |
|---|---|
| Which hand-shower model is offered? | Pause behavior belongs to that model. |
| Does its pause trickle or seal fully? | Both designs exist; the products checked trickle. |
| How is the pause operated? | Lever, dial, button or automatic trigger. |
| Which valve will be used? | The valve controls temperature; confirm which control stops the water. |
| What backflow protection is included? | A pause is not backflow protection. |
| What flow rating and labels apply? | Ratings and labels cover the shower, not the pause. |
Include with your request
- Shower layout with valve and outlets
- Valve type and any required standard
