Plumbing 2 sinks + 10L water heater + waste in shed

£200

Old Coulsdon, Greater London

11th Sep 2026

I’m fitting out a small garden prep kitchen in Coulsdon and need an experienced plumber to complete the water and waste connections. Everything is located very close together, so pipe runs are short. Scope: * connect incoming cold water supply * install hot/cold feeds to 2 sinks * connect a Flomasta 10L undersink stored water heater * fit suitable isolation valves * install the supplied pressure-relief valve and discharge arrangement in accordance with the manufacturer’s instructions * connect sink wastes and traps * connect both sink wastes into the existing waste outlet * surface-mount pipework neatly to the wall * pressure-test and check all joints for leaks The electrical connection to the water heater will be carried out separately by an electrician. I’m happy for the plumber either to supply the small plumbing materials or tell me exactly what to purchase beforehand. Please only respond if you have experience installing small unvented/stored water heaters and pressure-relief discharge pipework. Please quote a fixed labour price and indicate estimated material cost separately
