Product FAQs


Ask a Question

  • Is this tank compatible with the GE Profile™ Reverse Osmosis Premium Water Filtration System?

    Technically, yes. You should be able to connect this tank to this type of RO system. However, we do not recommend this. The GE Profile Premium uses a 2.3 Gallon tank. This 14-gallon tank would have 7 times the capacity, which means it would take MUCH longer to fill and you would have issues with pressure. 

    You should be able to use a 4-gallon tank with no issues and it would increase your capacity. Here is a link to ours if you are interested:


  • Does this tank have a 2" hole to fit the Top Mount Float Assembly your site offers? If not, which tanks do?

    No, the floats are designed for atmospheric tanks, not metal RO tanks.

  • How much PSI should a 14 gal tank have?

    5 to 7 PSI

  • Can this 14 gallon tank be added as an additional tank to supplement my 4.5 gallon tank without issue? in other words is it ok to mix and match storage tank sizes in an RO system?

    Yes, you can mix and match storage tanks. Make sure you have enough space wherever you plan on putting your tanks though, as a 14 gallong tank more than likely will not fit under a kitchen sink.

  • Can this tank be installed horizontal?

    Yes, absolutely.

  • Is it possible to get a 1/4 tank valve kit instead of 3/8?
    Do not select the 3/8” tank valve kit and order this ¼” valve instead; https://www.uswatersystems.com/john-guest-1-4-quick-connect-x-1-4-fpt-john-guest-elbow-valve.html
