Copper or Plastic

Why choose a Copper/Brass filter


The Pipefilters contain no plastic, they are smart and ultra reliable, their high performance, expected lifespan and simplicity to fit and clean make them quite unlike any other central heating magnetic filter on the market and they fit truly in-line.

Plastic is cheaper to produce and is derived from oil and it's properties change dependent upon time and temperature.

Copper and brass are highly respected in the plumbing industry, they are robust and dependable and more expensive to manufacture, they can work at higher temperatures and pressures and are trusted and respected as the best choice of materials for domestic plumbing operations 

We set out to make an unbreakable top quality filter for longer term use, not just a few years, time is on your side when you install a solid Johnson Magnetic Pipefilter.

They are simple to service, and are purposely made with fewer joints than other filters for maximum reliability, you can easily fit a 120 model under a combi boiler in a small kitchen cupboard where space is minimal.

They are basic in design and simple to work on they can be cleaned out and stripped down in minutes with basic plumbing knowledge, over and over again, with extra peace of mind, knowing the strong joints and threads can be tightened up with 100% confidence unlike a plastic threaded joint.

With no fancy push-fit fittings or plastic threads to strip the heavy duty brass connections just keep going and going leaving you with full confidence when you clean one out, they will not let you down.

How many times have you pulled on a plastic jar filter with the spanner and created a leak or have failed to open it, yes pure headache just waiting to happen.

Copper and Brass made to last...

Smart, high performance, reliable, affordable, serviceable, and great value for money, they will outlast the boiler and

The filters are handmade therefore no two filters will ever be the same, they are bespoke by design employing good old fashioned and trusted great British engineering at the heart of every finished product.

I developed this "least joint" simple design to provide ultra reliability and to be the best overhaul.
Every filter is handcrafted and individually soldered using traditional plumbing techniques and skilled craftsmanship

Magnetic heating filters are simply fantastic, all heating systems should have one, I never cease to be amazed at all the sub micron steel particulate and sludge (magnetite) they manage to trap and capture as the water flows through them. 

Our Neodymium magnetic cartridges are high temperature rated and so our filters can to be fitted into the hotter flow pipework. Sometimes you just can't get into a return pipe easily!

The magnetic elements are precision made by experts with over 50 years of technical know how and material sourcing expertise for the medical, food processing, electrical goods and motor vehicle component world.

The Pipefilter has been made to appeal to wiser homeowners, engineers, housing associations and councils who are looking for the best value filter, offering high performance, longevity, reliability and peace of mind. If you have a long term strategy and money saving aim, we offer the best value for money, give one a try and see!

How to clean a Pipefilter

Having fewer joints than other filters means, lower leakage risk. Just clean them out once a year during the boiler annual service by turning of the valves and simply removing the magnet housing or sleeve and rotate it, till the magnet slides out, then place the magnet vertically into a plastic bag or paper towel and hold the top element washer in one hand and wrap the other hand around the top of the element, drag the dirt off, in a rotating action and place it in a suitable bin.

Give the stainless steel magnetic element, brass and copper housing and rubber Grundfos pump type washers a good rinse under the tap. Replace the housing, washers and tighten the large valve nuts back onto the filter body.

If the filter has been fitted horizontal, open the air bleed/drain/dosing valve and just one valve lever slightly to bleed the air from the unit.

If the filter has been fitted vertically, air can be bled from the unit via the larger top valve nut by momentarily loosening it and opening just the bottom valve lever, tighten the top nut back up once the air has been purged out and water is present.
