FAQ – Pressure Washers Without an Outdoor Tap
1. Can I use a pressure washer without an outside tap?
Yes. Many models can draw water from buckets, tanks, or indoor tap connectors.
2. How much PSI do I need for car cleaning?
Between 1500–2000 PSI is usually ideal. More power can strip paint if used incorrectly.
3. Do cordless pressure washers work well?
Yes, for light and medium jobs. They’re best for bikes, cars, and patios, but not as strong as mains-powered units.
4. How do I connect an indoor tap?
You’ll need an indoor tap adapter, such as the Kärcher connector, which attaches to your faucet and allows you to run a hose to your washer.
5. What’s better – a bucket-fed or tap-fed washer?
If portability matters most, bucket-fed cordless units are ideal. If you want unlimited water, an indoor tap adapter with a corded washer is best.
Conclusion
Not having an outdoor tap doesn’t mean you can’t enjoy the power and convenience of a pressure washer. Whether you choose a cordless, bucket-fed model like the Worx Hydroshot, or a high-performance indoor-tap-compatible unit like the Kärcher K5 Premium, there’s a solution that fits your needs. Investing in the right model means more freedom, cleaner spaces, and less hassle.
