    Can’t do some tyre and rim combos with my track pump. CO2 works but seems to cause premature drying of the sealant.

    I had a go at the bottle method but it makes me a bit nervous. It all seems a bit fragile to be pumping up to 50 or 60 PSI

    Has anyone ever had any luck with a garden sprayer? They come with an inbuild pump so I presume you would just have to adapt the hoze to fit onto a valve? Do they get to a high enough pressure before the safety valve kicks in?

    Also I figure a 5L sprayer would be more effective than a 2L bottle for larger tyres (29ers) or at lower pressures since this is working on Boyle’s law.

    Yup,

    Garden sprayer works fine,I use a 2ltr for 26in tyres. I put an extra valve in place of the safety valve- motorbike valves are best.2 valves, one for in (it is just quicker with a track pump, and you get a meter) one for out with a hose and clip to go to the wheel.

    Will go and take a picture in a bit .

    yep.
    5 litre garden sprayer here. Very effective.
    Simply cut off the nozzle and replace it with the valve connector from your trackpump. Kinking the outlet hose over and securing it with a clip has been fine to allow sufficient volume and pressure to be built up.
    Undo the clip, unkink the hose, and the tyre seats immediately. 😀

    Yes, I have. 5l sprayer for just this. Basically, I removed everything downstream of the trigger, and replaced it with a short length of track pump hose, which fits snugly over a Prest valve. I find I need to remov the valve for to get enough flow rate to seat tyres.

    Done and it works. Much better than faffing with a track pump or CO2. Modified it after the trigger so it now ends with a presta valve (no core. Also allows me to pump it up with a track pump so I can see what the pressure is. Bit of tube to connect to a tyre.

    Safety valve cut in at 40psi so I “modded it” 😳 with a washer so it goes to 50psi. What pressure do you take your’s to.

    My safety valve is full of hot glue 🙂

    Pump up to 80 psi
