    • Pedestal: Affordable, easier to maintain, ideal for narrow pits.
    • Battery Backup: Activates during power outages for added protection.
  • Sizing Your Pump:
    • Measure vertical lift (height from sump pit to discharge point) and horizontal distance.
    • Match flow rate (GPM) with pump power (HP).
    • Use proper pipe size to minimize friction loss.
  • Key Features:
    • High-water alarm, check valve, and battery backup ensure reliability.
  • Professional Installation: Certified technicians ensure proper setup, extending pump lifespan and reducing risks.

Follow this guide to select, size, and install a sump pump that fits your needs, ensuring long-term protection for your home.

Sump Pump Types

Main Pump Types: Submersible, Pedestal, and Battery Backup

Submersible Pumps
These pumps combine the motor and pump into a single waterproof unit, allowing them to operate fully submerged in the sump pit. They are quiet, compact, and handle larger volumes of water and debris effectively.

Pedestal Pumps
A pedestal pump has its motor positioned above the sump pit, with only the pump section submerged. While they are louder than submersible pumps, they are more affordable and easier to maintain. Their slim design makes them ideal for narrow or shallow sump pits.

Battery Backup Systems
Battery backup pumps act as a secondary layer of protection, automatically activating during power outages or when the primary pump fails. They help prevent flooding until power is restored or the main pump is repaired.

Selecting Your Pump Type

Choosing the right pump depends on your specific needs and the conditions of your space.

Site and Flow Requirements

  • For finished basements with expensive flooring or stored items, a quiet submersible pump paired with a battery backup offers reliable protection.
  • If water seepage is light to moderate, a pedestal pump can handle the job efficiently.
  • For areas prone to heavy water flow or frequent flooding, a submersible pump provides the necessary capacity to manage the load.

Installation Space
Check the dimensions of your sump pit to ensure the pump fits properly. Submersible pumps require a deeper pit, while pedestal pumps need enough vertical space above the pit for the motor.

Once you’ve determined the type of pump you need, it’s time to focus on sizing it correctly.

How to Choose a Sump Pump? (Complete Sizing Guide …

How to Size Your Sump Pump

Choosing the right sump pump depends on two main factors: total dynamic head (which includes vertical lift, horizontal distance, and friction losses) and the required flow rate. Once you know the pump style you need, it’s time to calculate these variables to ensure the pump fits your setup.

Measuring Lift and Distance

To determine the total dynamic head, start by measuring the vertical lift – the height from the bottom of your sump pit to the discharge point. Then, add the length of the horizontal pipe and account for any elevation changes along the way.

For example, if you have an 8-foot pit and a 20-foot horizontal pipe, you’ll need a pump rated for at least 28 feet of head to handle the lift and friction.

Flow Rate and Power Requirements

Your pump should be able to handle the maximum amount of water your site might experience. Here’s a breakdown of flow rates and the corresponding pump power you’ll need:

Water Flow Total Head (ft) Minimum HP
Light (15–25 GPM) Up to 15 1/3 HP
Moderate (25–45 GPM) 15–25 1/2 HP
Heavy (45–60+ GPM) 25+ 3/4 HP

Pipe Size and Friction Loss

The diameter of your discharge pipe directly impacts friction loss. Here’s a quick guide:

  • Use 1.25-inch pipes for flows up to 30 GPM.
  • Use 1.5-inch pipes for flows between 30 and 45 GPM.
  • Use 2-inch pipes for flows above 45 GPM.

Keep in mind that every 90-degree elbow in the piping adds around 2 feet of head. To reduce friction and maintain efficiency, minimize bends or consider upsizing the pipe or selecting a pump with a higher head rating for longer or more complex runs.

What to Look for When Buying

Once you’ve calculated pump capacity and head, it’s time to ensure your chosen model is equipped with the right safety features.

Double-Check Your Sizing Calculations

Match your total dynamic head and flow-rate measurements to the pump specifications to ensure compatibility.

Key Safety Features to Consider

Make sure your pump includes these essential safety features:

  • High-water alarm: Alerts you when water reaches critical levels.
  • Check valve: Stops water from flowing back into the pump.
  • Battery backup: Keeps the pump running during power outages.

Pump Features Compared

Once you’ve determined the right size and safety features, it’s time to compare pump models side by side. With your pump type selected and sizing calculations complete, focus on the key features and power ratings to make your final choice.

Pump Types and Their Applications

  • Submersible: Operates quietly, handles high water volumes, and is ideal for deep pits due to its sealed motor.
  • Pedestal: More affordable and easier to service, though it’s noisier and best suited for narrow pits.
  • Battery Backup: Automatically activates during power outages, but offers limited flow and is best for emergencies.

Consider how these features align with your calculated head and flow rate to ensure the pump performs reliably.

Power and Flow Rate Considerations

Check that the motor power aligns with your flow-and-head calculations. Match the pump’s horsepower (HP) and gallons per minute (GPM) ratings to the head and flow you measured. Use the manufacturer’s performance curve to confirm the pump will operate effectively under your specific conditions.

Choose a pump with a capacity that matches your usual water volume, leaving some extra room for heavy rainfall or unexpected water inflows. This ensures your system can handle peak demands without fail.

Expert Installation and Support

Once you’ve selected the right pump, proper installation and support are essential for optimal performance.

Why Opt for Professional Installation

Professional installation ensures your system operates reliably. Certified technicians handle everything: confirming lift and flow calculations, positioning the pump correctly, making safe electrical connections, adhering to local regulations, and testing the system under real-world conditions.

How To Change a Whole House Water Filter – Replace Water …

About Lead Water Filters

Lead water filters are designed to reduce lead levels in drinking water, helping to make it safer for household use. Here’s a closer look at how they work and what you need to know.

How Lead Filters Work

These filters rely on a multi-stage system that typically includes activated carbon and ion exchange resin. As water passes through, these materials trap and hold lead particles, effectively reducing the lead content in the water.

Meeting Safety Standards

To ensure effectiveness, filters should meet NSF/ANSI Standard 53. This certification guarantees that the filter can lower lead levels to below the EPA’s limit of 0.015 mg/L.

When to Replace Filters

Follow the replacement schedule provided by the manufacturer. Factors like heavy water usage, local water conditions, or noticeable changes in water pressure or taste can signal the need for a new filter.

Required Tools and Materials

To replace a lead water filter without interruptions, make sure you have everything ready. Here’s a breakdown of the tools and materials you’ll need.

Basic Tools

These are the essentials for a standard filter replacement:

  • NSF/ANSI 53-certified replacement filter: Ensure it matches your system.
  • Adjustable Wrench: A 12-inch or larger wrench to loosen the filter housing.
  • Safety Gear:
    • Heavy-duty nitrile gloves
    • Safety goggles with side protection
    • N95 dust mask (useful during cleanup)
  • Collection Items:
    • A 2-gallon bucket or basin
    • Clean towels or rags
    • Leak-proof disposal bag for used filters

Additional Tools

These extras can make the job easier and improve results:

  • Filter Housing Wrench: Designed specifically for your filter model.
  • Plumber’s Tape: Use 1/2-inch PTFE tape to seal connections properly.
  • Cleaning Supplies:
    • Food-grade silicone lubricant
    • A 50/50 white vinegar and water solution
    • Soft-bristled brush for scrubbing
  • Testing Materials:
    • Water pressure gauge
    • EPA-certified lead testing kit for post-replacement checks
  • Documentation Tools:
    • Filter replacement log to track changes
    • Permanent marker for labeling dates

Keep these tools organized in a maintenance kit for future use. Store cleaning supplies separately to prevent contamination. Before starting, inspect all tools for any signs of wear or damage.

Safety Steps

Stick to these safety measures to safeguard your health and minimize contamination risks.

Shutting Off Water

  • Find the main water shutoff valve in your home.
  • Turn the valve clockwise to stop the water flow.
  • Open a faucet to release any leftover water in the pipes.
  • Allow about two minutes for the system to fully depressurize.

Protective Gear

Use the right protective equipment to keep yourself safe:

  • Nitrile gloves (heavy-duty)
  • Safety goggles

Proper Filter Disposal

Dispose of used filters in line with local disposal rules. Not sure what to do? Reach out to Hydrodynamics Inc. for expert assistance.

Replacement Instructions

Now that you’ve taken the necessary safety measures, let’s go through the filter replacement process step by step.

Removing the Old Filter

Start by placing a bucket underneath to catch any leftover water. Use a filter wrench to unscrew the filter housing by turning it counterclockwise. If the housing feels stuck, avoid forcing it to prevent damage to the threads. Be cautious – the filter will be heavy due to trapped water, so hold it securely while removing it. If it remains stuck, contact a certified technician for assistance.

Cleaning the Housing

Check the housing for any damage, worn O-rings, mineral deposits, thread issues, or signs of corrosion.

Clean the inside of the housing with a soft cloth, focusing on the sealing areas. Avoid abrasive materials or harsh chemicals that could harm the components. Once cleaned and inspected, you’re ready to move on to installing the new filter.

Installing the New Filter

When setting up the new filter, follow these steps:

  • Ensure the replacement filter matches your system’s specifications.
  • Double-check that the O-rings are seated correctly.
  • Confirm the filter is positioned properly (look for “FLOW” arrows to guide you).
  • Hand-tighten the housing first, then use the filter wrench for final tightening. Be careful not to overtighten.

Testing the System

Once the new filter is installed, slowly turn the water back on at the main valve. Open the nearest faucet to release any trapped air and inspect the filter housing for leaks. Let cold water run for about 5 minutes to flush the system and confirm all connections are sealed properly. If you encounter any problems during installation or testing, reach out to Hydrodynamics Inc. Their certified technicians are ready to help ensure your lead water filter is installed and working correctly.

Filter Care and Longevity

Keeping your lead water filter in good condition is key to ensuring it works properly and keeps your household water safe.

Replace your lead filter according to the manufacturer’s guidelines, usually every six months. This helps maintain its efficiency and extends its lifespan. Here are some signs it’s time for a replacement:

  • Slower water flow: Reduced water pressure might mean the filter is clogged.
  • Visible changes: Discoloration or debris buildup on the filter.
  • Timeframe: You’ve reached the replacement interval suggested by the manufacturer.
  • Water quality issues: Changes in taste, smell, or appearance of your water.
