Shower Installation in Portsmouth

Many properties around Albert Road and Elm Grove have original lead mains and small bore pipes that limit shower options. Electric showers work well here, but mixer showers often need pressure boosting or new supply pipes from the mains.

Portsmouth water is moderately hard (200-300mg/l calcium carbonate), which scales up shower heads and electric elements faster. We'll recommend models with easy-clean features and advise on descaling routines to extend component life.

Converted flats around Southsea often share incoming mains, so pressure drops when neighbours use water. Power showers with pumps work well here, but we'll check your lease first as some freeholders restrict pump installations due to noise.

Properties in areas like Paulsgrove and Cosham often have hot water cylinders in airing cupboards, which are ideal for mixer and power showers but need proper pipe sizing to avoid lukewarm water when the cylinder's heating up.

We'll run supply pipes from the nearest connection points to the shower location, fit isolation valves, and prep the waste connection. Expect noise from drilling and some dust. Water will be off for 2-3 hours while we connect to existing supplies.

We'll mark fixing positions, drill and plug the wall, then mount the shower unit securely. For electric showers, we'll make the water connections and leave the electrical connections for a qualified electrician. All joints are pressure tested before handover.

The waste pipe needs a minimum 40mm diameter and a fall of at least 1:40 to prevent backflow. If your shower tray is below the existing waste level, we may need to cut into the floor or use a waste pump system.

We'll test all temperatures, flows, and waste drainage before cleanup. For thermostatic mixers, we'll set the maximum temperature to prevent scalding. You'll get a demonstration of controls and maintenance requirements before we leave.

If you want to relocate a shower, the waste pipe routing often needs floor or wall modifications that affect structural timbers. Building Regulations may apply if you're altering drainage in properties built before 1965.

Installing a shower where there wasn't one means new supply pipes, waste connections, and often upgrades to existing pipework. The positioning affects drainage falls and may need Building Control approval for waste modifications.

Pump-assisted showers need specific pipe sizing, pump positioning for noise control, and electrical connections. They can't be fitted to combination boilers and need adequate cylinder recovery rates to work properly.

Temperature issues usually mean pressure imbalances, faulty thermostatic cartridges, or incorrectly sized pipework. DIY attempts often make it worse by disturbing valve settings or damaging cartridge seals.
