Home improvement solution for steadier water pressure and quieter plumbing across leisure and small domestic installations. Owners of motorhomes and caravan conversions will appreciate calmer taps and reduced pump noise from Seaflo Accumulator Tank. Is fitting one worthwhile for an existing water system?

⚡ At a Glance
  • Pressure Control: Smoother flow, quieter plumbing and reduced pump cycling
  • Best for: Motorhome and leisure users needing steadier tap and shower performance
  • Not ideal for: Systems that already maintain stable pressure without cycling issues

Internal bladder design separates air and water to stabilise pressure. Two snap-in port fittings and universal mounting allow straightforward installation in many setups.


Quieter plumbing and reduced water hammer - with internal rubber membrane

An internal rubber membrane separates the water chamber from a compressed air section, absorbing pressure spikes when taps close. That membrane prevents sudden pressure transients that cause banging noises in pipework.

Pipes become noticeably quieter and banging is minimised during tap changes. Suitable for leisure vehicles and small systems where water hammer is a common nuisance.

Longer pump life and lower battery drain - thanks to reduced cycling

Pressurised water stored in the accumulator reduces the number of pump starts by supplying short demands without firing the pump. Fewer start/stop cycles decrease mechanical wear and electrical consumption.

Pumps run less often, extending operational life and cutting battery draw in off-grid setups. Ideal for installations that rely on battery power and frequent short draws.

Quick install on new or existing systems - with snap-in port fittings

Two snap-in port fittings allow fast connection to common plumbing runs and a design suited for universal mounting, so the tank fits a variety of layouts. No specialised mounting brackets are required.

Installation is straightforward, with many users reporting easy fitting in motorhomes. Handy for retrofitting without major rework to existing pipework.

A: Yes. The internal rubber membrane absorbs pressure spikes and reviewers confirm quieter pipes and elimination of water hammer.

Q: Is the tank easy to fit in a motorhome?

A: Yes. Two snap-in port fittings and universal mounting allow simple fitting to new or existing systems, and users report straightforward installation in motorhomes.

Q: Does the accumulator reduce pump cycling and battery drain?

A: Yes. Stored pressurised water lowers pump starts, stabilising pressure while reducing cycling and battery consumption as noted in both descriptions and user feedback.

🏆 Our Verdict

Suited for motorhome owners and anyone with pump cycling or water hammer problems, the accumulator stabilises pressure and quiets plumbing. The internal rubber membrane, snap-in fittings and two year warranty make for a low-maintenance, easy-to-fit solution. Durable design and reduced pump wear point to good long-term value for leisure installations.
