Will a mains water booster pump fix a weak shower and slow-filling bath throughout my home, or should I look at a shower-only solution?

A mains booster pump is designed to fit onto your incoming cold mains and raise the pressure to the whole house, so it will improve weak showers and speed up bath fills across all outlets. If only one shower or tap is weak, a single-outlet option like the Salamander TapBoost can be a cheaper, targeted fix. For general poor pressure at several taps or multiple bathrooms, choose a mains booster such as the Salamander Homeboost or Stuart Turner StormBoost to give consistent, house-wide improvement.

How do I choose the right pressure (bar) and pump size for one bathroom versus several bathrooms?

For a single bathroom you’ll often be fine with lower-pressure units such as the Salamander Homeboost at around 1.6 bar, which improves shower performance and bath fill times. If you have multiple bathrooms or expect simultaneous use, step up to higher-pressure units like Stuart Turner StormBoost models at 2.5–3.2 bar to maintain flow when two or more outlets run. For small commercial premises or large houses, the bigger StormBoost 100–300 range or a TankBoost system with storage gives the capacity and steady pressure you need.

What's the difference between StormBoost, TankBoost and AccuBoost, and when would you choose a tanked system?

StormBoost are pressurised mains booster pumps that raise mains pressure directly, ideal where mains supply is steady but too low. TankBoost systems include a storage tank (100L, 200L, 350L or 450L) and deliver stored water at around 3.0 bar, so they're best when you want reserve volume for multiple simultaneous uses or if your mains flow is variable. AccuBoost refers to unpumped accumulator tanks (120L or 180L) which smooth pressure and reduce pump cycling; choose an accumulator where you need gentler pump operation rather than lots of extra stored water.

Can I install a single‑outlet booster like the TapBoost for a weak kitchen tap, or will that affect other fittings?

A single‑outlet TapBoost is made to increase pressure to one tap or shower only, so it will improve your kitchen tap without changing pressure elsewhere in the house. It’s a practical, cost-effective solution when an isolated outlet is the problem rather than whole-house low pressure. If you later find multiple fittings are weak, you can upgrade to a mains booster to raise pressure across all outlets.

How do I decide what tank capacity I need, are there rules of thumb for 100L versus 350L or 450L tanks?

Match tank capacity to household demand: a small home or single bathroom might only need a 100L or 120L option, while a family home with two or more bathrooms will benefit from 200L–350L to keep showers strong when more than one outlet runs. Larger properties or light commercial use should consider 350L–450L tanks so you have reserve volume and steady 3.0 bar output during peak use. a four‑bed house with two showers running at once will usually feel noticeably steadier with a 200–350L TankBoost than with a 100L tank.
