Reservoir Top-Off Kit

(15 reviews) Write a Review

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.

    As usual, Gary has taken it upon himself to offer an idiot proof turn key kit that is very well thought out!

    Top-Off Kit

    Posted by SoOkie on Mar 10th 2020

    I’ve been using this for about 2 weeks. This product is a must have in my book. I’m about 2 1/2 months into my first medical grow. I bought Gary’s 5 bucket DWC. I have a 20 gallon trash can hooked up to it. It is performing as advertised. Took my a couple of days to get the float just where I wanted it. At first I was worried about it overfilling . After about 3 days of checking it multiple times my worries have been squashed. Tomorrow afternoon I’m heading out on a 5 day vacation, the tent will be unattended. That being said I know the Top-Off kit will be doing it’s thing. Thanks PA Hydroponics and Gary for your very informative vids , it makes all the difference. Happy Growing Folks, take care all.✌️
