About this deal

There are quite a few 'surge damping' expansion tanks on the market. These vary in size, complexity and cost, but they all have two water connections and they are all fitted "in line". I think there is some confusion here, cut in and cut out pressures are controlled by pressure switch, they have nothing to do with accumulator settings. An accumulator is there purely to stop rapid cycling by delaying the drop, and rise, in pressure

Our collections by our couriers are happening as usual. As it stands, delivery times are not being affected too much. Please be aware though that Royal Mail and other couriers are sometimes prioritising essential items so please bear with us if your delivery takes slightly longer than expected. The accumulator may be placed anywhere in the pressurized side of the plumbing. The ports are non-directional in flow and do not have to be plumbed in line (one side can be plugged). The A20 is designed for universal use and is therefore an ideal addition to our Shurflo Trail King water pumps, previous models and all other types of pressure switch pumps. The Fiamma A20 Universal Expansion Tank is small and compact, not much bigger than a 750ml bottle of water. Extend the life of your pump and cut water consumption with theFiamma A20 universal expansion tank

Instructions

The Shurflo Accumulator Tank is a bladder type pressure storage vessel and pulsation-dampening device designed to hold water under pressure. The accumulator tank provides additional water storage to assist the pump in meeting the total demands of the system. It extends pressure switch-controlled pump life by reducing pump on-off pulsation. The accumulator is designed to reduce cycling pulsation and pressure spikes, increase the life of your pump and even save battery power. The Shurflo accumulator easily handles pressure requirements from 20 PSI to 125 PSI. I think one needs to be a bit careful with "nothing to do with", as there should be an interrelationship between accumulator pre-charge and the cut in setting of the pump's pressure switch. Fitting an expansion tank is simple enough in principle, but can be a real challenge if space is tight. All the expansion tanks I know of seem to require fitting in an upright position. There may also be a need to adapt the tank's water-connections if they don't match the type of water system used on the leisure vehicle. For example, Fiamma's A20 expansion tank is designed to connect to a traditional system using flexible water hoses and Jubilee-clips. Adaptation would be required to connect an A20 to a system using semi-rigid water pipework and push-fit connectors. I fitted the Whale product to my previous Herald motorhome in an attempt to cure spitting at the water-taps. However, I can't comment on its effectiveness as the problem turned out to be due to an air leak where the water pipework connected to the fresh-water tank. When I first see this valve I must admit I thought it was to drain any air in the system out. ..help.

Use a standard tire air pump and pressure gauge. The pre-charge valve stem cap MUST be tight to prevent air leakage.

It is supplied with straight and angled 13mm flexible hose connectors and self-tapping screws for fitting. Precharged at 0.9 bars (13 Psi) the Fiamma A20 can be charged with its special valve by a normal compressor so it can be adapted to all pressure switch pumps that are on the market. Installation Guide The universal expansion tank also saves on water and electricity, increasing the pump performance and prolonging the life of the pump, all for an outlay of around half the price of the pump. The tank builds up a head of water which under pressure comes out in a steady stream due to the internal pressurized diaphragm providing a smooth, surge-free continuous flow. The A20 can be dismantled for diaphragm operations if necessary. Can be adapted to a multitude of pressure switch pumps The little problem, which is more annoying than a problem is the sound from the pump. When any tap is used we get "water hammering"...this goes on for maybe 5/6 secs when the tap is closed. Yes, you can continue to return items as normal as long as you follow the government guidelines about leaving your house. SHURflo’s Pre-Pressurized Accumulator Tank smoothes water faucet pulsations and reduces pump cycling to keep water line pressure up and pump motors cool. The SHURflo® accumulator tank reduces plumbing system noise, increases the life of your pump and saves battery power. Coupler fitting is included.
