What size lines and what tank is compatible
For the Flint & Walling CPJ10B convertible jet pump, selecting the appropriate pipe sizes and pressure tank is crucial for optimal performance. Here’s a concise guide:

—

### 🔧 Pipe Sizing

**Suction Line (from well to pump):**
– **Size:** 1¼-inch diameter
– **Material:** Galvanized steel or PVC
– **Purpose:** Ensures adequate water flow and minimizes friction loss.

**Pressure Line (from pump to ejector in deep well setups):**
– **Size:** 1-inch diameter
– **Note:** Used in deep well installations where an ejector is placed in the well.

**Discharge Line (from pump to pressure tank):**
– **Size:** ¾-inch or 1-inch diameter
– **Recommendation:** Use 1-inch piping to reduce friction loss, especially over longer distances.

**Additional Tips:**
– **Unions:** Install near the pump for easy maintenance.
– **Slope:** Ensure suction lines slope slightly upward toward the pump to prevent air pockets.
– **Sealing:** Use Teflon tape or pipe dope on threaded connections to prevent leaks.

### 🛢️ Pressure Tank Compatibility

**Tank Type:**
– **Bladder or Diaphragm Tank:** Preferred for their maintenance-free operation and consistent performance.
– **Air-Over-Water Tank:** Requires an air volume control system to maintain the correct air-to-water ratio.

**Sizing Guidelines:**
– **General Rule:** The tank’s drawdown capacity (usable water before the pump cycles) should be at least one gallon per minute (GPM) of the pump’s capacity.
– **Example:** For a pump delivering 10 GPM, a tank with a 10-gallon drawdown capacity is recommended.

**Connection:**
– **Inlet Size:** Typically 1-inch NPT (National Pipe Thread) fitting.
– **Proximity:** Install the tank close to the pump to reduce pressure drop and prevent short cycling.

**Pressure Settings:**
– **Pump Pressure Switch:** Commonly set at 30/50 psi (pump turns on at 30 psi and off at 50 psi).
– **Tank Pre-Charge Pressure:** Should be 2 psi below the pump’s cut-in pressure (e.g., 28 psi for a 30/50 psi switch).

—

### ⚠️ Important Considerations

– **Pressure Relief Valve:** Install on the discharge line to protect the system from overpressure.
– **Check Valve:** Required in the suction line to maintain prime and prevent backflow.
– **Priming:** Ensure the pump and suction line are filled with water before startup to avoid damage.

I have one called water works – a 32 gallon bladder upright that I may buy – but I would rather buy a 20 gallon and save 100
Got it. Let’s do the math and logic behind whether a **20-gallon** pressure tank will serve you just as well as the **32-gallon Water Worker** for your **F&W CPJ10B** pump (1 HP, up to ~10 GPM typical output):

—

### 🧠 The Key Metric: **Drawdown Capacity**

This is how much water you can use before the pump kicks on. It depends on:
– **Tank size**
– **Pressure switch setting (e.g., 30/50 psi)**
– **Bladder type**

#### Drawdown at 30/50 PSI:
– **32-gallon tank** → ~9.3 gallons usable
– **20-gallon tank** → ~5.9 gallons usable

> 💡 *Rule of thumb:* 1 GPM of drawdown per 1 GPM of pump capacity to prevent short cycling.

—

### 🤔 So Is 20 Gal Enough?

#### YES — *If:*
– You’re not using more than ~6 GPM consistently
– You don’t mind the pump cycling a bit more frequently
– You’re on a budget and will monitor for wear

#### NO — *If:*
– You’re running irrigation, multi-fixture usage, or live in a big household
– You want the pump to last longer (fewer cycles = less wear)
– You’re avoiding noise and frequent pump operation

—

### 🧾 Verdict

– **20 gal = fine for small setups**, but watch the runtime cycles.
– **32 gal = better performance and longevity**, but costs more upfront.
– If you’re tight on space, budget, or usage is light—go 20.
– If you want peace of mind and fewer cycles—go 32.

Want a list of solid, cost-effective 20-gallon tanks with good warranties?
I need enough water for one shower – just me about 3 times a week, the toilet and the occasional dishwashing
Perfect—your use case is super light. Let’s break it down:

—

### 🧼 **Water Use Breakdown:**
– **One shower**: ~10–15 gallons (low-flow head)
– **Toilet flush**: ~1.6 gallons
– **Dishwashing by hand**: ~2–6 gallons (depends on method)
– **Total per day**: ~15–20 gallons max

But here’s the trick: **you don’t need all of that from the tank at once**. You just need **enough drawdown** to avoid short-cycling the pump while you’re using water.

—

### ✅ 20-Gallon Bladder Tank = Smart Fit

– **Drawdown (30/50 psi setting)**: ~5.9 gallons
– That’s more than enough to let your shower run for 1–2 minutes before the pump kicks in, and it’ll cycle just once or twice per shower.
– For toilet flushes and dishwashing, it handles those easily with minimal cycles.

—

### 💡 Recommendation

**Buy the 20-gallon** and pocket the savings.
It’s totally adequate for:
– Solo use
– Light, infrequent water draw
– Budget-conscious installs

Just set the pressure switch to **30/50 psi**, pre-charge the tank to **28 psi**, and you’re golden. Want me to list a few good 20-gallon tanks to consider?
is the foot valve go by other names>
Yes—**foot valve** goes by a few other names or near-equivalents depending on context and region. Here’s the breakdown:

—

### 🦶 What Is a Foot Valve?
A **foot valve** is a **check valve at the end of a well’s suction pipe**, usually with a **screen** to keep debris out. It:
– **Prevents backflow** (holds the prime)
– **Lets water in** but not out
– **Sits at the bottom of the well**

—

### 🔄 Alternate Names or Related Terms

—

### ⚠️ Don’t Confuse With:
– **Ball valves** – Manual shut-off valves
– **Backflow preventers** – Used on discharge side in potable systems
– **Pressure relief valves** – Used to prevent over-pressurization

—

If you’re buying one, search for **“foot valve for shallow well jet pump”** or match the pipe size (usually 1¼” or 1½”). Want help picking the right one for your system?
