This kit can be used to keep water levels topped off in your recirculating hydroponic system, it can be used with many types of systems that have a reservoir ** except for ebb and flo or flood and drain hydroponic systems. We recommend running you system for a week or 2 before deciding how high or low to mount the float valve, people run there systems at different water levels and that is why we wont pre drill top off kits on our systems, sorry we hope you understand.- Gary

This kit includes:
1 - 1/2" Hydrologic float valve
1 - 1/2" drain bulkhead
1 - 1/2" elbow
5 foot of 1/2" black tubing

- Hydro-Logic® Float Valve - 1/2 in Barbed

This float valve comes with a 1/2 in barbed fitting. Adjustable water level and can be mounted horizontally or vertically. Allows you to fill any tank or reservoir unattended—never flood your garden again! All plastic and stainless steel materials. Better than brass and fully adjustable.

- Hydro Flow Ebb & Flow Tub Outlet Fitting 1/2 in (13mm) (10/Bag)
- Hydrofarm Active Aqua 1/2" Elbow Connector

- Hydrofarm 1/2" black tubing. Use our sturdy black vinyl tubing, which is FDA-approved and BPA-free, for your irrigation systems and tanks, and to complete your own hydroponic systems. The material is easy to cut to size, but will remain strong and reliable.  

Manufactured using high quality materials. Hydro Flow® Tub Outlet Fittings each come with 2 gaskets ensuring a water tight seal.

    This is just a whole lot easier than doing it yourself and the customer service can't be beat.

    This Top-Off Kit is a life saver

    Posted by Nathan on Oct 19th 2021

    Amazing for when your plants hit the pre-flowering and flowering stages as they drink so much water it's crazy. To not have this would be no fun checking and manually filling all the time. Thanks again Gary for the suggestion, it made all the difference in the world in regards to worrying about water levels every day or every other day. Helps you focus on steering pH as well with you top off reservoir. Thanks again!

    A no brainer

    Posted by Ryan on Oct 4th 2021

    I see this as a must include in your setup. For the price, the ability to keep your water level (and %k) exactly where you want it for a prolonged time is too good to pass up.

    Top off kit, deburing tool and pump

    Posted by Ed on Jul 7th 2021

    I bought the top off kit, deburing tool and pump. All three products are top notch and work well for my system. I will buy more products from PA hydroponics. I also love Gary’s YouTube videos. I learned a lot from these videos.
