I want to buy a new leisure battery. I work alone and I have a shurflo pump and a van system. Would a 90Ah 12v leisure battery see my through a typical 8 hour working day?

Yes, it should do. Do remember that each Shurflo pump can draw around 4 amps an hour. If you have a controller, then that will be much less.I want to buy a new leisure battery.

Thank you for your help, I appreciate itYes, it should do. Do remember that each Shurflo pump can draw around 4 amps an hour. If you have a controller, then that will be much less.
A 90amph lead acid battery has a useable capacity of 45 amps, as you don't want it to drop below 50% capacity. So ideally, you will need to recharge your battery every night.
Although you might work for 8 hours, your actual washing time (the time the pump is actually pumping water) will be less than that. I once estimated our pumps run for about 50% of our working day on a compact round. If a bit of travelling time is involved, then that time will be reduced.
Today we had a gutter clear, fascia and gutter clean, a conservatory roof clean and then the windows. Started with a completely fully charged leisure battery. The first hour was clearing the gutters with a vacuum cleaner. I then started the diesel heater. I believe the two of us spent around 3 hours combined cleaning. The pumps were running probably 80% of the time. At the end, I switched the heater off then packed away. We used 14 amps from my 105 amph leisure battery.
