Can you acidify tapwater?

I've got some blueberries in ericacaceous compost in tubs. Unfortunately because we are in rented accommodation I can't put a waterbutt in... so I have been watering with tap water but I know this is not ideal. This might be crazy but could you,  for example, pop a capful of vinegar in to acidify the water?  Or am I better off continuing as I am and replacing the compost next year?  🤔

    No it won't work.
    You'll need to get a large container for collecting rainwater. A plastic dustbin or similar would do, or just buckets and basins .  :)

    As fg says above it wont work.
    Making water more acidic won't remove the hardness that's caused by calcium and the like.
    Reverse Osmosis water would do the trick, but it's very wasteful - 1 gallon of RO would use between 3-5 gallons of water.

    Thanks both, thought it sounded too simplistic  :D

    We're fortunate up here as our tapwater is soft, although we also don't have to water stuff very often either  ;)

    You'll just have to swap to strawberries @Julia1983, or move north.... :D

     :D  I've got strawberries too so at least I might get a decent crop there!  I'll have to try and get a few rain buckets on the go  :)

    A cheap umbrella, opened upside down with a hole made near the centre placed over a bucket and weighed-down with a couple of bricks would catch a lot more than an open bucket.  Or anything similar made out of what you have available (eg plastic sheet, old compost bags etc. and a few bits of wood, fashioned into something which will catch rain over a wider area and channel it into a bucket.)
    A trowel in the hand is worth a thousand lost under a bush.

    Get you @BobTheGardener - with your  'fashioned into something'  :D

    You're right - a bigger area will work really well, and no one will be going anywhere when it's raining so there should be plenty of brollies going to waste  ;)
    Good luck anyway @Julia1983 :)

    Entirely Geoff Hamilton's fault!  May he rest in peace. :)

    Indeed so @BobTheGardener. What a gem he was  :)

    It would be good if the BBC re-ran all his programmes for us while in lockdown.
