When it comes to PVC piping systems for residential, commercial, and industrial use, few standards are more trusted than ASTM D1785. At 247Garden, we supply PVC pipes and fittings that meet or exceed this critical specification, ensuring quality, durability, and versatility for both pressure-rated and non-pressure systems.
ASTM D1785 is a specification published by ASTM International that covers polyvinyl chloride (PVC) plastic pipe in Schedule 40, 80, and 120. These pipes are designed for pressure applications—including potable water distribution, irrigation, and industrial fluid handling—but are also widely used in drain, waste, and vent (DWV) systems.
This standard defines important characteristics of the pipe, such as:
The versatility of ASTM D1785 PVC pipe makes it a go-to solution for both new installations and retrofit projects.
All three schedules conform to ASTM D1785 and offer compatibility with standard PVC fittings made to ASTM D2466 (Schedule 40) and ASTM D2467 (Schedule 80).
For proper installation, Schedule 40, 80, and 120 pipes that meet ASTM D1785 should be joined using:
Make sure the cement and primer meet ASTM D2564 standards for pressure applications. When applied properly, the solvent welding process creates a permanent and leak-free joint.
ASTM D1785 PVC pipe is compatible with a wide range of fittings including:
Cellular core PVC pipe manufactured under ASTM F891 is designed for non-pressure DWV applications only. While it can be used in conjunction with D1785 pipe for gravity-flow systems, it should never be used where pressure containment is required.
At 247Garden, we understand the importance of using the right materials for the right job. ASTM D1785 PVC pipe offers the strength, reliability, and compatibility you need whether you're handling pressure flow or DWV systems.
Complete your next project with confidence using 247Garden's NSF-certified Schedule 40 and Schedule 80 PVC fittings—manufactured to meet ASTM D2466 and D2467 standards for quality and reliability.

A Female Reducing Bushing with a Male Spigot x Female NPT configuration is a specialized PVC fitting designed to adapt a larger socket or hub to a smaller FNPT (female-threaded) outlet. This type of fitting—sometimes informally referred to as a female reducing ring—features a male spigot end that fits into a socket or hub, and an internal female National Pipe Thread (FNPT) connection that accepts a smaller-diameter male-threaded pipe or fitting.
To allow a reduction in threaded size inside a socket fitting without adding bulk or unnecessary transitions. It’s a clean and space-saving solution for downsizing from a large hub to a smaller FNPT thread connection.
Let’s say you have a 3" Schedule 40 coupling and need to connect a 1" threaded ball valve. Instead of using a full-size bushing or multiple reducers, you can solvent weld a 3" spigot x 1" FNPT female reducing bushing into the coupling and thread in the 1" valve directly.
At 247Garden, we offer a complete line of Schedule 40 and Schedule 80 PVC Female Reducing Bushings in spigot x FNPT configurations. Our fittings are:
Whether you’re retrofitting a manifold or building a brand-new PVC system, 247Garden has the fittings to keep your build clean, compact, and reliable.

Dosatron injectors are widely used for precise, proportional dosing of fertilizers, chemicals, or additives into irrigation and water systems. Whether you manage a greenhouse, farm, or industrial operation, knowing the right PVC fittings for your Dosatron system is key to creating a leak-free, efficient setup.
A Dosatron is a water-powered proportional dosing pump. It uses the flow of water through the unit to inject a precise amount of concentrate (like fertilizer or sanitizer) into the water line. This dosing is directly proportional to the water flow — no electricity required.
Dosatrons come in various models with different inlet and outlet connection sizes based on their flow rate capacity and application.
PVC Fittings help connect your Dosatron system to the water source and delivery lines. Using the correct PVC fitting types, sizes and specs ensures:
Schedule 80 PVC fittings have thicker walls compared to Schedule 40, which makes them stronger and more durable. Here’s why SCH 80 is often the better choice for Dosatron systems:
Schedule 80 PVC fittings can handle higher internal pressures without cracking or failing. This is important in Dosatron setups where pressure fluctuations may occur or where the system operates under higher pressures than typical irrigation lines.
The thicker walls make SCH 80 fittings more resistant to impact, abrasion, and environmental stress — including UV exposure and physical knocks — extending the life of your irrigation or chemical injection system.
Because the fittings are more robust, they maintain a tighter seal, reducing the risk of leaks around threaded joints or solvent-welded connections.
If your Dosatron system injects fertilizers, acids, or other chemicals, SCH 80 fittings generally offer better chemical resistance due to their thicker walls and better material density.
Dosatron systems require regular servicing and disassembly. SCH 80 fittings stand up better to repeated handling, installation, and removal without deforming or wearing out quickly.
Schedule 40 PVC fittings are the industry standard for many irrigation and plumbing projects because they are:
SCH40 fittings work well for many Dosatron users and provide reliable performance at a good price. But if you want added durability, higher pressure tolerance, and longer lifespan—especially in commercial or industrial settings—Schedule 80 is usually the better investment.
Unions are special fittings that connect two pipes or connect your Dosatron to plumbing, allowing quick disassembly without cutting pipes.
When it comes to durability and reliability, especially in demanding irrigation and chemical injection setups, Schedule 80 PVC fittings stand out for their thicker walls and higher pressure ratings compared to Schedule 40. This makes them ideal for Dosatron systems where you want extra peace of mind against leaks, cracks, or damage from environmental stress.
Fitting Type | Size Options | Purpose |
---|---|---|
Schedule 80 PVC Unions | 3/4", 1", 1.5", 2" | Easy removal and maintenance of Dosatron injectors |
Schedule 80 PVC Adapters (Threaded x Slip) | 3/4", 1", 1.5", 2" | Connect Dosatron threaded ports to PVC pipe |
Schedule 80 PVC Elbows (90°, 45°) | 3/4", 1", 1.5", 2" | Change pipe direction without leaks |
Schedule 80 PVC Check Valve Housings | Match your system size | Protect Dosatron from backflow |
Schedule 80 PVC Strainers | Match your system size | Prevent debris from entering Dosatron |
Choosing the correct fittings for your Dosatron system is crucial for a leak-free, efficient setup. While 1" threaded or slip fittings are the most common for residential and light commercial use, larger or smaller Dosatron models require 3/4", 1.5", or 2" connections.
Including unions in your setup is highly recommended for easy removal and maintenance. Paired with check valves and strainers, proper fittings ensure your Dosatron delivers accurate dosing and long-lasting performance.
While both schedule 40 and schedule 80 are great for most Dosatron system, by using schedule 80 stuff, you can have a more powerful and reliable system that guarantees better performance than schedule 40s.
Pairing your Dosatron system with high-quality Schedule 80 PVC fittings from 247Garden ensures long-lasting durability, leak-free connections, and easy maintenance. Investing in the right fittings upfront can save time, money, and headaches down the road.

When durability and performance matter, Schedule 80 PVC Wye Fittings (Y Fittings) deliver the strength and reliability you need. Whether you're working on a high-pressure piping system, chemical processing setup, or industrial infrastructure project, a SCH80 Y fittings are engineered to perform in the most demanding environments.
A Wye or Y fitting allows for the smooth merging or splitting of flow in a piping system, typically at a 45-degree angle. Unlike a T-fitting, which creates sharp directional changes, a Y fitting ensures better fluid dynamics by reducing turbulence and maintaining flow efficiency.
Benefits of using a Y fitting:
Wye fittings are used in a wide range of settings:
Wherever you need to branch off from a main line while maintaining optimal flow, a Y fitting is the right solution.
Schedule 80 PVC fittings are built with thicker walls and higher pressure ratings compared to Schedule 40. While Schedule 40 is suitable for many residential and light-duty applications, Schedule 80 is preferred for commercial and industrial projects where system strength, heat resistance, and pressure demands are higher.
Advantages of Schedule 80 over Schedule 40:
Choosing SCH80 is a practical upgrade when reliability and longevity are essential.
Wye fittings may also be referred to as:
Understanding these terms can help ensure you're ordering the right component for your system design.

A pipe union is a type of plumbing fitting designed to connect two pipes together while allowing them to be easily disconnected and reconnected without cutting the pipe. Unlike a regular coupling, which is usually permanent (glued, welded, or soldered), a union provides a reusable connection that can be taken apart and reassembled.
What is an EPDM Union?
An EPDM Union refers to a pipe union that uses an EPDM (Ethylene Propylene Diene Monomer) rubber O-ring as its sealing element. It is typically used in PVC (polyvinyl chloride) piping systems to allow for easy disconnection and reconnection of pipe sections without cutting or gluing.
The PVC union consists of:
If a PVC union is assembled without an EPDM O-ring:
An EPDM O-ring in a PVC union is essential for creating a durable, flexible, and watertight seal. Without it, the union is prone to leaks, reduced reliability, and more frequent maintenance. Including the EPDM O-ring ensures the system performs safely and efficiently in water and chemical applications.

When it comes to PVC plumbing projects—whether you're building irrigation systems, hydroponic setups, residential water lines or any high pressure chemical system—leaks are not only frustrating, they can also lead to major water damage, pressure loss, and costly repairs. At 247Garden, we offer top-quality Schedule 40 and Schedule 80 PVC fittings that meet or exceed ASTM D2466, D2464, D2467, F1970, UPC-PW and ANSI standards. But even the best fittings can leak if installation mistakes are made.
Here are the 10 most common reasons PVC pipes and fittings start to leak—and how to avoid them.
Solution:
Always use a PVC primer (such as purple primer) to clean and soften the surfaces before applying PVC solvent cement. This step ensures a chemical weld between the pipe and fitting.
Not all cements are compatible with all types of PVC fittings or applications. For example, using regular cement on a pressure system or a SCH80 joint can cause leaks under stress.
Solution:
For SCH40 or SCH80 pressure systems, use a cement that matches your application—such as heavy-duty gray cement for SCH80, or medium-body clear cement for SCH40. Confirm compatibility with pressure ratings and temperature limits.
PVC doesn't seal well without adhesive. If you're assembling a system by dry-fitting and then gluing afterward, the alignment might shift slightly, causing weak bonding and eventual leaks.
Solution:
Dry-fit only to test alignment, then immediately glue the joint while holding it firmly in place for at least 30 seconds to set.
Once PVC cement is applied and the parts are bonded, any twisting or repositioning will weaken the joint and can introduce micro-fractures or air gaps.
Solution:
Hold the pipe and fitting in a fixed position for 30–60 seconds after joining to ensure a full chemical weld.
Threaded SCH40 or SCH80 fittings like adapters and caps are easily damaged by over-torquing, which can crack the fitting and lead to slow leaks.
Solution:
Use thread sealant (not Teflon tape) made for plastic fittings and hand-tighten with only a slight additional turn using a wrench. Stop if you feel resistance.
Solution:
Use a plastic-compatible thread sealant or thread paste (PTFE-free if required). Apply evenly and avoid over-wrapping.
Temperature fluctuations can cause PVC pipes to expand or contract, especially if they are installed tightly without room to move. This can stress joints and create cracks or leaks over time.
Solution:
Allow room for thermal movement, especially in long runs. Use expansion joints or flexible couplings where needed.
Not all PVC fittings are rated the same. DWV fittings, for example, are not designed for pressure systems. Using a DWV fitting in a pressurized line is a guaranteed leak.
Solution:
Use only pressure-rated SCH40 or SCH80 PVC fittings like those offered by 247Garden. All our fittings meet NSF and ANSI standards and conform to ASTM D2466, D2464, D2467, and F1970, making them ideal for water supply, irrigation, and structural applications.
Here are two more common mistakes that can cause PVC pipe leaks, to add to the blog:
A sloppy or uneven pipe cut leads to poor surface contact inside the fitting, which means the solvent cement won’t bond the materials evenly. This often causes small gaps that leak under pressure.
Solution:
Use a fine-toothed saw or PVC pipe cutter to make clean, square cuts. Always deburr and bevel the pipe ends with sandpaper or a deburring tool to ensure a smooth, snug fit.
Some users pressure test or run water through the system too soon after gluing. PVC cement needs time to cure and form a solid chemical weld—rushing this process can cause immediate or delayed leaks.
Solution:
Follow the cement manufacturer’s instructions for curing time. Typically, wait 15 minutes for handling, and at least 2 hours (up to 24 hours) before pressure testing, depending on temperature and pipe size.
Let me know if you'd like the full blog updated with these final two included.
