More Information on cast iron parts

At EasyMerchant, we carry a wide and varied range of cast drainage stack components.

From the hoppers and bends you'll need to make your stack fit the house perfectly - to components that will make sure your drains work perfectly for years to come.

Why cast iron guttering?

Originally, half round iron drainage components were created with a lifespan of around 40-50 years in mind - but many stacks have long outlived this! It's not uncommon to find systems still working perfectly - even if they were fitted over 100 years ago.

As such, some people like to repair or replace like-for-like - and in some cases, a listed conservation status on a premises means cast iron rainwater channels must be replaced with similar products to preserve the heritage of the building.

Whether you're installing cast products purely for aesthetic reasons - or you're doing so to keep within the law, we've got you covered. Not only can we provide the parts you see here - but we can also source and supply less commonly used fittings - so don't hesitate to get in touch with our customer service team if there's anything you need that you can't see here.

How much are cast iron downpipes worth?

Some metals can be worth a good amount when taken to a scrap metal dealers - but cast iron does not attract the same premium as a more desirable metal - like copper for instance - and comes nowhere near lead prices.

As such, old cast iron parts are not worth a great deal as scrap - especially since new cast iron versions can be bought as affordably as they are at EasyMerchant.

If you're planning to sell old cast iron downpipes or other parts - and perhaps swap it for a more practical and lower-maintenance plastic set up, your best bet for selling your old parts would be using a reclamation yard.

How to remove an upright section of your cast iron guttering stack

Removing any part of an old metal set up can be a challenge - especially if it's been fixed in place for a long time - or has been re-fixed over the years to keep it secure.

If the downpipe is fixed in concrete at the bottom, you're faced with very little option other than cutting it off - unless of course you plan to excavate some of the underground pipework too.

Generally, the brackets that hold the pipe in place up the run will be held in place with large pins. Sometimes gentle back and forth movement of the entire section will ease these out of their resting place - although it's absolutely vital that you ensure the parts are secured or supported before trying to remove it from the wall - as it will be heavy and could fall and cause damage if it comes away suddenly. It's a good idea to have someone else working with you ready to keep it in place if you're attempting removal.

If the pins holding the fixings/accessories don't come away easily, you might need to use an angle grinder to remove the heads that are securing the brackets. Alternatively, you could see if using a heatgun helps to get them moving - especially if you can pry the brackets at the same time.

Again - it's important to remember that cast iron rainwater parts weigh a lot - so make sure you're working carefully and don't take any risks when you're working at height.

How to repair cast iron gutters and cast iron downpipes

With half round cast iron gutters often dating back to the early 1900s, it's not at all uncommon to find that they're in need of substantial repairs when closely inspected - especially where parts have been repainted in order to hide corrosion over the years.

Before you begin working on your stack, it's important to make sure it's well supported. These large upright pipes don't often get subjected to move movement - so if you're working on it, you could dislodge corroded fittings - leaving very heavy components unsupported. Carry out a through inspection before you begin work.

You'll need the following tools to carry out a repair to your downpipe:

  • Steel/brass brushes
  • Hammer
  • Chisel
  • Metal epoxy repair paste
  • Putty knife
  • Suitable PPE

You should first clean away as much corrosion as possible using your wire brushes. Make sure you're thorough at this stage - as corrosion that is not removed can spread - even if painted over with a rust inhibitor.

When holes are cleaned and free from rust, you should use a two-part epoxy to completely fill the hole. You'll need to allow the product to dry completely before the downpipe is used again - so it's a job best saved for a few days of rain-free weather.
