2 Outdoor Taps to 1 Garden Hose

Hi. I have recently installed an outdoor hot water tap directly next to my existing cold water tap. So I now have 2 outdoor taps (hot and cold). The idea behind this was that my toddler will not get in his paddling pool if it's freezing cold, so I thought installing a hot tap for easy access would help me out. However, I'd now like to create a mixer with some sort of connector into both taps, giving me one outlet that I can connect to my hosepipe. Like the old, retro push-on-taps shower kind of thing. I can't find anything like this for outdoor use with the connector for one outlet. Everything seems to go the other way: i.e. connecting one tap into 2 outlets. To reiterate, I need to connect 2 taps to one hose outlet. Does anything like this exist?

    I've a feeling there's a problem with doing this as there's a possibility of water from the hot pipe getting into the mains water system. I'm not sure of the technicalities and I may be wrong but  it's something I would check on.

    You could use a splitter in reverse (something like this), but as Dove says there could be a pressure difference that may cause a problem.
    Cold water at mains pressure could force the hot water to go in reverse as it were. I think if you have a combi boiler it may not be the case, but def check it out first.

    Water regs outdoor taps should have double check valves

    I just to used to add a few buckets of warmer water to the paddling pool when my boys were toddlers. Didn’t cost a thing.

    If the paddling pool is in the sun it will warm up by itself and toddlers, in my experience, are impervious to cold paddling pools.   Install a sink and use the hot water for something useful like washing your plant pots!

    Wouldn't the simplest solution be to buy a second hosepipe?  Or part fill the pool with cold, then switch over and top up with hot.

    I did the same as Brightstar when mine were little, chucked in a couple of buckets of hot to take the chill off 😁.

    Thanks for the advice, folks.

    I have just had the hot tap fitted and so would assume it meets all regs - is there a foolproof way of assessing whether it has double check valves to prevent reverse flow?

    The Y connector and 2-way splitter in reverse are things I looked at, but the taps both aim vertically down and so wouldn't clip straight on. I guess I'd need a short section of hose with appropriate connections and either end - does that exist as well?

    On the note re toddlers being impervious to cold paddling pools...I can assure mine is not. Hence why I've installed a hot water tap!  :D
    Up to this point we have just done the same re chucking in a couple of buckets of hot water. But I had the bright idea of installing this second tap, so I could in effect "mix" it to a temperature that I could just fill it with immediately - thinking I was saving myself some effort in the long term, but it appears I have just made my life harder. The really annoying this is that I could have had an outdoor mixer tap installed instead of the 2 individual taps - I went for the latter because it was cheaper, thinking that something would exist to allow me to mix it. I am now regretting it...

    put a connector on each tap, add about 0.5m of hose onto each one, add another connector ( "male" end )on the end of those 0.5m lengths , then connect the hose ( going to the pool ) via a "female" end to one tap, then swap to the other.
    No need for Y connectors, no chance of water mixing.
