Description

If you have two bathrooms running off one combi boiler and both showers run weak, then the two SP22S twin packs are the best option for you.

With two bathrooms on one combi, the morning rush becomes a competition. Whoever showers second gets the weaker deal, and every open tap in between makes both showers surge and fade. A combi can only share out the water it’s given, so as demand rises the pressure at each shower falls.

Whilst you may have been told two decent showers on one combi isn’t possible, there is now a pump pack that fixes it.

The SP22S for combi boilers is a pack of two WRAS-approved automatic booster pumps — the same pump as our SP2B uses, twice over, with a single 3-amp transformer and the linking cables included. Fit one pump on the hot pipe feeding each shower and one on the cold so every shower gets its own protection: pressure boosted, flow held steady, temperature kept level when taps open elsewhere. Each pump protects flow rates up to 6 L/min for showers; 8.5 L/min for mixed tap flow.

Both pumps detect flow and start by themselves — no switches, nothing to turn on. WRAS approval means the Water Regulations Advisory Scheme — the UK’s independent water safety certification — has verified the pumps are safe to fit to the pipes that supply your home.

Q: What’s the difference between the SP22S and buying two SP2Bs?

A: The pumps are the same. The SP22S pack gives you both pumps with one 3-amp transformer and the cables to link them, so it’s the simpler and better-value way to do two showers.

Q: Will the SP22S stop my boiler cutting out?

A: Yes & No — Yes, if it’s just low flow from the boiler that’s the problem but low mains pressure is a different problem with a different fix. If the boiler delivers only scalding hot water or shuts off during use, you probably need the SP21S fitted on the incoming mains before the boiler.

Q: Can the pipes feeding each bathroom be identified near the boiler?

A: Yes — You will feel which pipes get hot when you run each shower separately

Whilst boosting the hot and cold throughout a home or to an individual shower or tap a SP22S is perfect for Combi Boiler Systems.

If a flushing toilet or a running cold tap makes the shower fade and boosting only the hot won’t hold it. One pump on the hot and one on the cold keeps both feeds protected, so the shower holds steady.

The SP22S for gravity systems is two WRAS-approved automatic booster pumps — one fitted on the hot feed, one on the cold. With both feeds boosted and protected, the shower holds its pressure and its temperature If your home has a cold water tank in the loft or in an airing cupboard — as many older UK homes, flats and HMOs do and— your shower pressure is set by gravity alone. The height between the tank and your shower head is all the push the water gets, and in most homes that’s only a few inches, which can make all your showers and taps feel weak.

Whilst you may have been told your only options are a bulky, expensive power shower or a new system, there is now a simpler DIY and permanent fix. In most homes it’s only the hot that’s lagging behind, so a single pump on the hot feed is all it takes to get up to four times the pressure and twice the flow. A SP22S gives you the option of boosted hot and cold showers.

Both pumps detect flow and start by themselves, share a single 3-amp transformer, and fit on the pipes after the vent pipe using the reducing sets included. WRAS approval means the UK’s independent water safety scheme has verified they’re safe for your home’s supply.
