We saved the contractor an impressive 71% materials cost when he went for the PP-R swap we recommended for this plant room job.


The original specification was to use MDPE Pressure Pipe electrofusion, but we were able to advise on the suitability, and cost saving, of switching to PP-R.


The requirement was:

• A header in 63mm dia. to connect water to each flat
• 90mm dia. from the storage tank to the pump. Connections including isolation/strainer valves
• 32mm dia. from the storage tank to the sprinkler system including isolation valves

In MDPE, as specified, materials would have cost £6,767.35.  In Wefatherm PP-R, the cost was just £1974.50 – a saving of 71%.


Plumbing subcontractor MDO Pipe Fitting Solutions came in and completed the job in just 2 days.


Our main involvement on this new build site of 9 apartments (11 bathrooms) in Deptford, London, was through merchant Professional Plumbing Supplies Limited who supplied all bathroom materials and the Wefatherm PP-R.


But, as always, we were delighted to add value with our knowledge and advice, resulting in a spectacular cost saving for the contractor.
