AY McDonald 3/4″ 6005 Series Stop and Waste Valve
The AY McDonald 6005 series provides a 3/4″ FNPT x FNPT stop and waste valve built in brass. It is designed for curb box installations with a Minnesota-style stop and drain feature. Best for homeowners upgrading curb-side shutoffs or replacing aged valves in residential lines. The threaded top aids secure connections in restricted spaces. A limitation is that it relies on threaded joints, which require proper threading tools and sealing compounds to avoid leaks.
3/4″ KEY STOP VALVE
The 3/4″ KEY STOP VALVE is a robust, key-operated option suited for rough plumbing tasks and shutoff points along lines. Best for technicians or handy homeowners performing controlled shutoffs in limited spaces. It is manufactured in Taiwan, which may influence availability of replacement parts. Consider this choice if you need a simple key-operated solution with straightforward installation, but verify compatibility with your piping type before purchase.
3/4 inch No Lead Cast Brass Stop And Waste Valve With Solder Cup Connectors
Midline Valve’s 3/4 inch No Lead Cast Brass Stop and Waste Valve with solder cup connectors targets copper pipe installations. Best for plumbing setups where solder cup joints are standard. It uses cast brass for durability and ensures lead-free operation. This option is ideal if your system uses copper piping and you want a solder-friendly valve. A potential limitation is the need for soldering work, which may require more time and skill than compression fittings.
225-2-34-34 Threaded Ground Key Stop and Drain Valve
This bronze-ground-key valve is designed for curb or ground-level shutoffs. It operates with a threaded ground key and is sized at 0.75 in. Best for outdoor or exterior shutoff points, where a robust, corrosion-resistant bronze body is advantageous. It may require a compatible key tool for operation, which is an important consideration for maintenance access and theft resistance.
AY McDonald 3/4″ FIP x FIP Ball Valve Curb Stop
The AY McDonald 3/4″ FIP x FIP Ball Valve Curb Stop uses female iron pipe connections for secure, leak-resistant shutoffs. This option is best for systems with standard FIP threads and where a ball valve provides quick, full-port shutoff. Its curb-stop design suits exterior or accessible indoor curb boxes. A limitation is the reliance on FIP threads, so verify anti-lead and compatibility with your existing piping before installing.
3/4 inch No Lead Cast Brass Stop And Waste Valve With Female Threaded IPS Connectors
Midline Valve’s 3/4 inch No Lead Cast Brass Stop and Waste Valve with female threaded IPS connectors targets IPS piping. Best for installations that require standard IPS threading and a lead-free brass body. It can be a good choice when replacement parts and compatibility with IPS fittings are priorities. A caution is ensuring the IPS threading matches your existing piping to prevent leaks or the need for adapters.
Model 76001 3/4″ Stop & Drain Ball Curb Valve
The Model 76001 valve is a no-lead brass stop and drain valve designed for curb box installations with FNPT x FNPT ends. It offers full-port shut-off and corrosion resistance. Best for residential water service shutoffs where compliance with lead-free regulations is important. A potential limitation is availability of replacement parts in some regions.
