Good afternoon,i have a 1000ltr ibc full of rainwater and i want to
water my allotment but the pressure from the hose is pitifull,i do
have a generator which is a honda driven which says 220 on the
side.Can anyone advise on what size water pump i should buy to be able
to get a reasonable pressure?,as always,tiagonsesen

3 bar 50litre/min should be ample (I have one in my domestic H&C
system)

Metric measure of pressure. 1 bar = 14.5 p.s.i.

Pressure - 1 Atmosphere is more or less 1 bar.

Remember when weather forcasts said "it is 1008 millibars over London
tonight..."?

Three times atmospheric pressure. Personally I would double that. Six
bar will provide a decent squirt out of the hose.

The OP wants to water his plants not pressure wash 'em. B-)

Our outside tap has less than 30' head (approx 1 bar) and is fed by a
long and complex bit of 15mm pipe. It's flow/pressure is only just
too low. Something around 2 or 3 bar would be fine.

From when I was testing my house supply, the most you'll get through a 1/2"
hose is about 15-20 l/min at 4-5 bar (I used a hose to test the drains I'd
constructed).

55l/m is what I get through the 1/2" supply pipe at 7.5 bar

spose it depends on how long/convoluted your hose is? pressure vs flow
etc

55l/m is what I get through the 1/2" supply pipe at 7.5 bar

aye, 50l/min was what my pump was sized for to backwash a pH filter
through 1" pipework.
Through the taps of course I don't see that throughput (thankfully for
hot water!!)

Of course This was "typical smooth bore garden hose" in a "typical garden
hose length". I had to use 3 hoses all tapped off 22mm pipe to get the full
flow of 50+l/min (I was testing a sink, dishwasher and washing machine
drain point I'd just laid in, all fed off the same 50mm waste pipe, to make
sure I couldn't overload them or their u-traps.

50 l/min thru 22mm AND 3 hose pipe adaptors??

If we're talking allotments then a skip-grade CH circulator (aka central
heating pump) would do nicely. Keep skip-diving for replacements when they
eventually pack up. Or ask a friendly plumbing & heating installer for old
but working ones taken out when they replace boilers.

Biggest fiddle might be making connection to the container. Assuming the
pump and genny are next to the container, and you don't have more than about
30 metres of hose something like this should be fine

220 volts. That tells you nothing about the power output. How big is
the motor? Can you estimate the horsepower and/or wattage? 750 watts
is equivalent to one horsepower. You will not get much more than 60% of
the motor power converted to water power. You should be able to buy a
single stage radial flow pump that will operate on single phase power.
Radial flow pumps will give more pressure and less flow while axial flow
pumps give more flow at less pressure.
