Can FloFit be connected directly to a central heating boiler?

FloPlast recommend that a minimum run of 1 metre of copper pipe should be installed prior to the first FloFit connection, for further details please refer to BS5955: Part B.

Can FloFit be fitted directly to compression fittings?

FloFit pipes are suitable for use with compression fittings, however a pipe insert must always be used. Compression fittings with a short pipe stop depth or hard olives should not be used with plastic pipe. Hard olives can be replaced with soft copper olives.

Can FloFit be fitted directly to copper pipes?

Yes, as long as the pipe conforms to BS EN 1057.

FloPlast recommend that a minimum distance of 450mm of copper pipe should be installed between the last solder joint and the first FloFit joint to ensure residual flux solder does not come in contact with the fittings.

Flofit fittings should not be fitted or installed on stainless steel pipes, chrome plated copper tube, Imperial sized copper or plain brass spigot ended fittings.

Can FloFit be used for external pipes under ground?

FloFit is designed and classified for internal use only.

Can FloFit be used with alternative plastic systems?

The system is available in 10mm, 15mm and 22mm diameter compatible with all plastic plumbing systems conforming to BS 7291.

Can FloFit be used with Combi Boilers?

Yes, as long as 1m of copper pipe is used straight from the boiler before the first FloFit connection

Can I re-use FloFit fittings?

Yes, FloFit it is a fully demountable system and providing that the O-ring has not been damaged, the fitting can be re-used.

Can the FloFit range be used for underfloor heating?

Yes, FloFit is fine to use for underfloor heating.

Can the FloFit system be re-used?

Yes, the system is fully demountable and providing that the ‘o’ ring inside of the fittings are not damaged then they are fine to re-use.

Can you fit the FloFit system directly onto copper pipe?

Yes, copper pipe will fit directly into FloFit fittings and there is no need to use a pipe insert.

Do central heating inhibitors or descalents affect FloFit?

Central heating inhibitors and descalents do not adversely affect FloFit.

For further advice, companies such as:

  • Fernox (0870 601 5000) or
  • Sentinel (0151 420 9563)

should be contacted.

Do I need to use pipe inserts and collet clips on every fitting?

Yes, It is essential that pipe inserts and collet clips are used on all installations of the FloFit system.
The pipe inserts need to be pushed all the way into the pipe, up to the small lip at the end of the insert and help keep the pipe rigid.
This will also prevent the fitting from crushing the pipe when fitted together and potentially causing leaks.

Does soft water affect FloFit?

How does FloFit work?

Each socket consists of an EPDM O-ring and a collet (grip ring) containing the stainless steel grip teeth. When the pipe is inserted into the socket it passes through the collet and the O-ring to form a seal. The pipe is fully inserted when it stops in the bottom of the socket. The pipe should be fully locked into the collet clip – however to ensure a tight fit, pull the pipe firmly backwards from the fitting.

Joints are easy to make, details as follows:

When making a joint with FloFit, ensure that the pipe has been cut square and free from burrs, scratches and sharp edges. FloPlast recommend that all pipes are cut with pipe cutters and not hacksaws.

Do not use damaged or scratched pipe as this could cause a leak.

Before assembling the joint, ensure that the appropriate pipe insert has been inserted into the pipe. All joints with either FloFit fittings or compression fittings must include the correct pipe insert.

Insert the pipe into the fitting, ensuring it passes through the 0-ring until it reaches the stop point. We recommend that you mark the insertion depth on the pipe as measured from the end of the pipe insert to ensure that the pipe has reached its stop point.  Please refer to the table in our assembly procedures in the Hot & Cold Plumbling Systems section of the website.
Check the assembly to ensure that the pipe is fully locked by pulling the pipe away from the fitting.

To identify hot or cold water circuits, replace the white collet clip with a red or blue collet clip, supplied separately.

To dismantle the FloFit fittings, remove the collet clip, push the collet face towards the body of the fitting and pull the pipe out of the socket. No tools are required to dismantle FloFit fittings.

Is FloFit affected by Chlorine?

The FloFit range of pipe and fittings are suitable for carrying normal levels of chlorine found in domestic water supply systems. Whilst the FloFit system can be disinfected with chlorinated water using the concentration level, contact period and procedures described in BS6700, it is not suitable for use on systems where the water contains high levels of chlorine e.g. swimming pools, fountains etc., or areas of high chlorine.

Is FloFit affected by paints and chemicals?

FloFit can be painted with either water or oil based paints. Avoid all contact with cellulose or solvent based paints, thinners, strippers, agressive cleaning fluids or acid-based descalents.

Is FloFit affected by Soldering flux?

FloPlast recommend that no fluxes of any form should be allowed to come into contact with FloFit pipe or fittings. When fluxes are employed in the same area as FloFit, care should be taken to ensure contact does not take place, by ensuring that cloths used on the pipe work are clean and free from flux contamination. Ensure that when handling the pipe work, contamination is avoided through hand contact etc.

Is the FloFit system compatible with other manufactures?

The FloFit system can be used with other manufactures systems but whatever make of fittings you use you must make sure that you use their inserts as well.
The FloPlast PEX pipe will say to use FloPlast inserts, use the insert that matches the fitting.

Is there a guarantee with the FloFit range?

Yes, a 25 year guarantee is offered with the FloFit range.

Should I thermally insulate FloFit pipes and fittings?

The spacing around the piping allows thermal insulation to be fitted in accordance with the Building Regulations or designated specifications.

What different pipes are available and what are the differences between them?

There are two different pipe, PEX and Polybutylene.

PEX pipe is white, more heat retaining and more rigid so is better for straight line installations.
Polybutylene pipe is more pliable so is better for installations around corners.

What is the maximum temperature that the FloFit will withstand?

Temperatures of up to 85°c will be fine to be passed through the system.

What type of systems can FloFit be used on?

The FloFit system is suitable for all domestic and small commerical hot & cold-water installations, including most central heating systems:

  • Mains fed indirect cold water systems
  • Vented and unvented hot water systems
  • Vented and sealed central heating system

FloFit must not be used for:

  • Gas applications
  • Oil fuel applications
  • High pressure air supply

Will FloFit change the taste of water passing through it?

No, FloFit has been fully approved for use in hot & cold water by WRAS. As such, FloFit has been tested by”The Water Quality Centre” and complies with the recommendations of BS6920.

Do you have point of sale material?
