When a recent survey on a Channel Island 22 found both water closet seacocks in need of replacement – including the through-hull fittings – owner Gary Stones decided to take on the task himself. With a keen interest in boat maintenance, and after diving into owner forums and online research, Gary chose Groco as his preferred brand. Armed with step-by-step guidance from Groco’s technical bulletin, he quickly discovered how straightforward the process can be when using the right products.
Here are Gary’s chosen components – and why they worked for him.
High-Quality Bronze Components
Gary selected the Groco Full Flow In-Line Ball Valves – IBV Series (BSPP Thread) as the foundation of his installation. Precision-engineered from solid bronze (C83600) and fully ISO-9093-1 compliant, these valves offer proven durability below the waterline and ease of maintenance above it.
Why Gary chose them
Each valve features:
- A solid stainless-steel handle with ratchet point
- An innovative grub screw that allows the handle rotation to be reversed if accidentally fitted against a bulkhead
- A drain plug for quick and easy water removal while the valve remains in place
- A grease zerk nipple (included with all valves 1¼” and above) allowing simple lubrication without removing the valve
Small details like these made the IBV Series an ideal choice for a confident, DIY-friendly upgrade.
Secure, Professional Installation
Gary wanted to ensure a robust installation that would stand up to insurance inspection and give him long-term peace of mind.
He chose Groco Flanged Adaptors – IBVF Series to ensure loads during valve operation were evenly distributed across the hull skin. This helped minimise direct stress on the through-hull fittings – crucial for long-term safety and structural integrity.
To complete the setup, Groco Backing Blocks provided the perfect support platform, creating a strong, watertight, professional-looking installation.
Added Protection and Easy Maintenance
To finish the system, Gary installed Groco Hull Inlet Strainers – RSC Series. These deliver reliable primary filtration for cooling water, protecting engines and generators while maintaining excellent flow rates.
The result: a corrosion-resistant, confidence-boosting upgrade that saved time, money, and future maintenance effort.
Gary’s Experience
“Purchasing through Marine Products Direct was straightforward. Knowing what I needed helped, but the team were keen to understand fully what I was after and help guide me through the installation,” says Gary Stones, owner of the Channel Island 22.
“I did the work myself with the help of the install guide and honestly it was more straightforward than I had imagined. She’s now ready for next season on the water.”
Safeguard Another Key Ingress Point
Marine Products Direct also stock Lasdrop dripless shaft seals – a low-maintenance, high-quality solution where the propeller shaft meets the hull. Ideal for owners looking to further enhance vessel safety and reliability.
