Tuscan EN877 Drain is a socketless cast iron drainage system made to BS EN 877, for below-ground drainage and suspended drainage runs in basements, undercrofts and plant areas. Plain-ended pipes and fittings are joined with bolted couplings. The result is a rigid, non-combustible system that resists crushing and root ingress, and copes with the loads found under buildings and hard landscaping.

Frequently asked questions

What sizes is the Tuscan EN877 Drain P Trap with Bottom Door available in?

It is available in 100mm (HD4050), 150mm (HD6050).

Why does a P trap need an access door?

Traps collect debris. The door lets you clear the trap in place rather than breaking the joints.

Can a P trap be used on a rainwater pipe?

Yes, where rainwater discharges into a combined sewer. The trap stops sewer gases venting through the downpipe.

We have just purchased some cast iron radiators and they have a slightly uneven texture to the surface. What can we do about this.

We have just purchased some cast iron radiators and they have a slightly uneven texture to the surface. What can we do about this.

Casting of iron is an imperfect processs. It is possible with some cast iron radiators that you will get minor imperfections in the surface finish. When radiators are painted this will reduce and over the years every additional coat of paint applied will provide a smoother more equal finish.

Is cast iron soil pipe suitable for listed buildings?

Is cast iron soil pipe suitable for listed buildings?

Yes. Cast iron is the original material for external soil stacks on most period buildings, and like-for-like replacement in cast iron is usually what conservation officers expect. Check with your local planning authority whether listed building consent is needed for the works.

What is the advantage of a louvre-face airbrick over a square-grid pattern?

What is the advantage of a louvre-face airbrick over a square-grid pattern?

The louvre face provides directional airflow and offers some resistance to driven rain entering the subfloor void, making it a practical choice for exposed elevations or properties in areas with significant prevailing wind and rainfall. The square-grid (school board) pattern offers a larger open ventilation area but less weather protection.

What building types is the H544 cast iron hopper head suited to?

What building types is the H530 cast iron hopper head suited to?

The H530 measures 330mm wide x 150mm deep x 350mm high, making it well suited to Georgian and Victorian terraces, where a compact, narrow footprint is needed.

What finishes are available on your cast iron hopper heads?

What finishes are available on your cast iron hopper heads?

Is a cast iron hopper head suitable for use on a listed building?

Is a cast iron hopper head suitable for use on a listed building?

We are renovating a barn and would like to know what the anticipated life expectancy of your guttering and pipework would be.

We are renovating a barn and would like to know what the anticipated life expectancy of your guttering and pipework would be.

The standards for our cast iron gutters and pipes have remained remarkably constant for many years. The physical properties of cast iron are sustained throughout its lifetime thus maintaining its effectiveness. Coupled with is durability and proper maintenance, we would expect our traditional cast iron rainwater products to last for over 50 years under normal conditions.

My house has a plastic guttering system. Can I use your brackets to replace my exisiting broken ones?

My house has a plastic guttering system. Can I use your brackets to replace my exisiting broken ones?

Our brackets are more commonly used on cast iron rainwater systems. Unlike plastic, cast iron is heavy and the weight keeps the gutter in position. As such our brackets do not normally have retaining clips which could lead to plastic or lightweight gutters blowing out of the bracket. The profile of your gutter should match that of our bracket but without the weight to keep it in place you may well encounter problems in bad weather.
