Is that persistent drip under your kitchen sink driving you crazy? You are not alone. A worn-out strainer basket is one of the most common causes of minor but annoying kitchen leaks, often leading to water damage if ignored. Finding the right replacement part can feel overwhelming with so many generic options available. This guide focuses specifically on the Plumb Pak PP820 37 Strainer Basket Basin Sink 1, a reliable solution designed to restore your sink’s functionality and stop leaks for good. Whether you are a seasoned DIYer or a first-time homeowner, we will walk you through everything you need to know about this essential plumbing component.
What Is the Plumb Pak PP820 37 Strainer Basket?
Before diving into installation, it is crucial to understand exactly what this part is. The Plumb Pak PP820-37 is a high-quality replacement strainer body and basket assembly. It is engineered to fit standard kitchen sink openings, typically measuring 3.5 inches in diameter.
Unlike cheap plastic alternatives, this unit is constructed from durable materials designed to withstand daily wear and tear, hot water exposure, and heavy food waste. The “Basin Sink 1” designation often refers to its compatibility with single-bowl setups or standard drop-in sinks commonly found in American homes.

Why Choose Plumb Pak Over Generic Brands?
When searching for “Plumb Pak PP820 37 Strainer Basket Basin Sink 1,” you might see cheaper, unbranded alternatives. However, experienced plumbers often recommend sticking with established brands like Plumb Pak for several reasons.
Durability and Longevity
Generic strainers often use thin metal that bends easily during tightening, leading to improper seals. Plumb Pak uses thicker gauge metal, ensuring the threads remain intact even after years of use. According to industry standards, a high-quality stainless steel or plated brass strainer can last 10–15 years, whereas low-quality zinc alloys may corrode within 2–3 years.
Precision Engineering
A leak-free seal depends on perfect alignment. Plumb Pak components are manufactured with tight tolerances, ensuring the rubber gasket compresses evenly. This reduces the risk of human error during installation.
Availability of Support
As a major brand, Plumb Pak parts are widely documented. If you run into issues, finding troubleshooting guides or compatible accessories is much easier than with obscure generic imports.
Step-by-Step Installation Guide
Replacing a sink strainer is a manageable DIY project. Follow these steps to install your Plumb Pak PP820 37 Strainer Basket Basin Sink 1 correctly.
Tools You Will Need
- Adjustable wrench or channel locks
- Plumber’s putty or silicone sealant
- Clean rag
- Bucket (to catch residual water)
Step 1: Remove the Old Strainer
First, disconnect the tailpiece from the bottom of the existing strainer. Use your wrench to loosen the large locking nut underneath the sink. Once the nut is loose, push the old strainer up from below and pull it out from the top. Clean the sink hole thoroughly, removing any old plumber’s putty or debris.
Step 2: Prepare the New Strainer
Take your new Plumb Pak PP820-37. Apply a rope of plumber’s putty around the underside of the strainer flange. Alternatively, you can use a bead of 100% silicone sealant. Note: Putty is traditional and easier to clean up; silicone offers a stronger waterproof bond but takes longer to cure.
Step 3: Insert the Strainer
Place the strainer into the sink opening from the top. Press down firmly to squeeze out excess putty. From underneath, slide the rubber gasket onto the threaded body, followed by the friction ring and the locking nut.
Step 4: Tighten Securely
Hand-tighten the locking nut first to ensure alignment. Then, use your wrench to tighten it further. Be careful not to overtighten. Overtightening can crack the sink material (especially if it is porcelain or composite) or distort the rubber gasket, causing leaks. A snug fit is sufficient.
Step 5: Reconnect and Test
Reattach the tailpiece and P-trap. Run water into the sink and check for leaks underneath. If you see drips, slightly tighten the locking nut. Wipe away any excess putty that squeezed out around the rim.
Common Problems and Troubleshooting
Even with a high-quality part like the Plumb Pak PP820 37 Strainer Basket Basin Sink 1, issues can arise. Here is how to handle them.
| Problem | Possible Cause | Solution |
|---|---|---|
| Leak at the rim | Insufficient putty/sealant | Remove strainer, reapply putty, and reinstall. |
| Leak at the nut | Loose locking nut or misaligned gasket | Tighten the nut slightly. Ensure the gasket is flat. |
| Strainer spins freely | Threads stripped or cross-threaded | Check threads. Do not force. Ensure proper alignment. |
| Water drains slowly | Debris in basket or pipe | Clean the basket. Check the P-trap for clogs. |
Compatibility Check: Will It Fit Your Sink?
One of the most frequent questions users ask is about compatibility. The Plumb Pak PP820-37 is designed for standard 3.5-inch openings. This is the industry standard for most kitchen sinks manufactured in the US over the last 50 years.
However, if you have a custom granite countertop sink or an older European-style sink, measure the diameter of the hole before purchasing. If your hole is larger (e.g., 4 inches), you will need a different model or an adapter kit. For more information on standard plumbing dimensions, you can refer to general plumbing guidelines on Wikipedia.
Maintenance Tips for Longer Life
To get the most out of your new strainer:
- Avoid Harsh Chemicals: Do not pour drain cleaners directly into the strainer basket. These chemicals can corrode the metal finish over time.
- Clean Regularly: Remove food debris daily to prevent buildup in the threads.
- Check the Gasket Annually: Every year, inspect the rubber gasket underneath for signs of cracking or hardening. Replace it if necessary to prevent future leaks.
FAQ Section
Q1: Is the Plumb Pak PP820-37 made of stainless steel?
A: The Plumb Pak PP820 series typically features a durable metal construction with a corrosion-resistant finish. While some models are fully stainless steel, others use high-grade plated brass. Check the specific packaging for material details, but rest assured it is built to resist rust in typical kitchen environments.
Q2: Can I use this strainer for a bathroom sink?
A: Generally, no. Bathroom sinks usually have smaller drain openings (1.25 to 1.5 inches). The PP820-37 is designed for the larger 3.5-inch openings found in kitchen sinks. Using it in a bathroom sink would require an incompatible adapter and is not recommended.
Q3: Do I need plumber’s putty or silicone?
A: Both work well. Plumber’s putty is easier to use and allows for adjustments during installation. Silicone provides a more permanent, flexible seal but requires 24 hours to fully cure before exposing it to water. For most DIYers, putty is the preferred choice for ease of use.
Q4: Why is my new strainer still leaking after installation?
A: The most common cause is an uneven application of plumber’s putty or a misaligned rubber gasket. Ensure the gasket is seated perfectly flat against the bottom of the sink. Also, verify that the locking nut is tight but not distorted. If leaks persist, remove the unit and reapply the sealant.
Q5: How long does installation take?
A: For someone with basic tools, replacing a sink strainer typically takes 15–30 minutes. This includes removing the old unit, cleaning the area, and installing the new Plumb Pak PP820-37.
Q6: Is this part compatible with garbage disposals?
A: Yes, the Plumb Pak PP820-37 is compatible with standard garbage disposal units. The tailpiece connection is standard, allowing easy attachment to disposal mounts or direct P-trap connections.
