Why Under Sink Grease Arrestor is Necessary
From my experience, having an under sink grease arrestor is absolutely essential in any kitchen. I’ve noticed that grease and oil from washing dishes can easily clog the drains over time, leading to slow drainage and costly plumbing repairs. The grease arrestor acts as a barrier, capturing fats, oils, and grease before they enter the pipes, which helps keep everything flowing smoothly.
I also appreciate how it prevents unpleasant odors caused by trapped grease buildup in the plumbing system. Without this device, my kitchen often smelled foul after heavy cooking sessions. Installing an under sink grease arrestor gave me peace of mind knowing that my drains are protected and my kitchen stays cleaner and more hygienic.
Overall, it’s a simple addition that saves me from frequent plumbing headaches and contributes to a more efficient and odor-free kitchen environment. I highly recommend it for anyone who cooks regularly and wants to avoid grease-related drain problems.
My Buying Guides on ‘Under Sink Grease Arrestor’
When I first started looking for an under sink grease arrestor, I quickly realized how important it is to choose the right one. These devices help prevent grease from clogging your plumbing and causing costly damage. Here’s what I learned during my search, which I hope will help you pick the best grease arrestor for your needs.
Understanding What an Under Sink Grease Arrestor Is
An under sink grease arrestor is a small unit installed beneath your kitchen sink that traps grease and solid particles before they enter your plumbing system. I found that having one is essential, especially if you do a lot of cooking with oils and fats, as it keeps your pipes clear and reduces the risk of blockages.
Key Features to Look For
When I was comparing products, these were the features that mattered the most:
- Capacity: Make sure the arrestor can handle the volume of grease your household or business produces. I checked the size and volume specs to ensure it matched my kitchen’s output.
- Material Quality: Stainless steel models tend to be more durable and easier to clean. I avoided plastic units because they felt less sturdy.
- Ease of Installation: Since I wanted a quick setup, I looked for models that come with clear instructions and all necessary fittings.
- Maintenance: A grease arrestor that’s easy to clean saves a lot of hassle. I preferred units with removable baskets or screens.
- Compliance: Depending on where you live, local plumbing codes might require certain certifications or standards. I made sure the product met these to avoid any issues.
Types of Under Sink Grease Arrestors
During my research, I found there are generally two types:
- Passive Arrestors: These rely on gravity and a simple baffle system to separate grease. They are affordable and low maintenance but might not be enough for heavy grease loads.
- Active or Mechanical Arrestors: These use filters or pumps to improve grease separation. They tend to be more effective but can be pricier and require more upkeep.
I chose a passive model for my home kitchen because it balanced cost and efficiency well for my needs.
Installation Tips from My Experience
Installing the grease arrestor under the sink was straightforward but here are some tips I found helpful:
- Turn off the water supply before starting.
- Measure your space carefully to ensure a good fit.
- Follow the manufacturer’s instructions closely.
- Consider hiring a plumber if you’re not confident with plumbing work.
- Test the system after installation by running water and checking for leaks.
Maintenance and Cleaning
Regular cleaning is crucial. I set a schedule to clean out the trapped grease every few weeks, depending on usage. Most models have a removable basket or screen, which makes this job much easier. Avoid using harsh chemicals, as they can damage the arrestor or pipes.
Price and Warranty Considerations
Prices vary widely. I found that investing a bit more upfront for a quality product saved me money on repairs later. Also, check the warranty period and what it covers. A good warranty gives peace of mind.
Final Thoughts
Choosing the right under sink grease arrestor made a big difference in maintaining my kitchen plumbing. By focusing on capacity, material, ease of maintenance, and local compliance, I found a model that works perfectly for me. I recommend doing your homework and selecting a grease arrestor that fits your specific kitchen needs. It’s a small investment that pays off in preventing costly plumbing issues.
