On the 23rd June 2026 Shower Power Booster launched a free online Product Selection Quiz to help UK homeowners fix weak showers and poor water pressure in minutes
Built to find the simplest fix, not the priciest
Unlike a typical product recommender, the quiz is engineered to find the simplest solution to fix your problem at minimum cost and effort. Around 80% of customers get everything they need from a single SP2B, our most popular and most affordable booster.
On a gravity-fed system, for example, a single SP2B boosting an upstairs shower running at a feeble three litres a minute can quadruple the hot pressure and double the mixed flow to six litres a minute — what we call a “Perfect Shower”. Where a home genuinely needs more, a double boost SP22S can boost the flow to 6.5 litres a minute. There are other reasons why a SP22S might be needed (as outlined in the quiz) but you can always upgrade later with our SP1U and SP2U pumps.
The quiz is built on years of feedback from real customers and in partnership with Alan Wright, the inventor of the Shower Power Booster, and the systems they’ve fixed. The answer you get is grounded in what’s actually worked in thousands of UK homes.
“If I were one of the 80% of customers, and I were doing the work myself, I would buy the SP2B when the quiz suggests — it’s the most affordable and simplest to install. Because the SP21S costs just a little bit more than an SP2B, I could be persuaded to always recommend an SP21S if a plumber fits the Shower Power Booster, because of its ability to provide more boost. But by keeping costs low, we turn a smile on a customer’s face into a big smile — and that’s priceless.” — Alan Wright
Honest guidance, full support
Shower Power Booster has been deliberately transparent about the quiz’s limits because customer service remains its highest priority. A small number of setups are difficult to assess from a questionnaire, and the quiz advises those customers to call before ordering.
Every pump is backed by a two-year warranty as standard and a 30-day return policy — plus the option to speak to a real person by calling +44 (0)1928 620 099 or emailing SPB@flowflex.com.
Most UK homes can achieve a stronger, steadier shower for around £143, with the pump fitted in minutes — no electrician or plumber required. For those who want to use a plumber, we have a list of recommended plumbers here.
