PSW TRADE SUPPLIERS LTD Central Heating Pump Rubber Type Pump Valve WASHERS Sold as (Pair) (Two Pairs)

Heating Pump Isolation Valve has a slow leak, so I buy a spanner and washer (2). This washer fitted perfectly and unlike a inferior fibre type, was thicker, so lest tightening was needed and the washer's seal/lifetime will be considerably longer.

..I wish Amazon had specified that a new Grundfos pump includes these washers in the box. Instead, Amazon offered these as "items often bought together [i.e. with the pump].." so I wrongly assumed I needed to buy them separately.

Fitted fine and do the job well.

As described

Only bought because so call reduced price pump did not come without washers ,but had to return pump so not required.
