TMV2 Thermostatic Mixing Valve Install

New TMV2 thermostatic mixing valve in on a basin — fresh copper to both inlets, outlet dialled in at 41°C and signed off. Standard care-home / vulnerable-user job, takes me about an hour once the old valves are out.

Cold Water Storage Tank Drain-Down & Legionella Clean

Loft tank dropped, scrubbed and chlorinated — classic L8 tank clean for a landlord that needed sign-off paperwork by Friday. Pump going in here, water out the door, fresh and certified by the time I left.

Varem Potable Expansion Vessel — Unvented System Service

Old expansion vessel had lost its charge — classic case, owner kept getting safety discharge from the tundish. Stripped it out, fitted a new 12 L Varem, pre-charge set, copper tidied up. System back up inside a couple of hours.

Ariston Andris Lux Under-Sink Point-of-Use Water Heater

Ariston 10 L under-sink heater in — instant hot water right at the tap, no more waiting 30 seconds for the run from the cylinder. Red and blue isolation valves so the next plumber (or me, on a service) can drop it out without drama.

Cold Water Tank Ball Float Valve Repair & Adjustment

Tank kept overflowing into the warning pipe every fill cycle — old brass ball valve had worn its seat. Stripped, new washer in, float arm reset so it shuts off cleanly. Five-minute fix once you know what you're looking at.

Mikrofill 3 Pressurisation Unit — Drain-Off Valve & Expansion Vessel Install

Commercial sealed system that had been nuisance-tripping for weeks. Fitted a proper drain-off valve, rebalanced the expansion vessel, and got the Mikrofill back to a steady 1.9 bar. Tidied the pipework while I was at it — easier next time anyone's in there.

TMV Strainer Filter Service & Clean

TMV inlet strainer pulled out on annual service — packed with limescale and grit from the local supply. Cleaned, refitted, blended temp back where it should be. Saves the customer £200 on a needless valve swap.

TMV Blended-Outlet Temperature Calibration Check

Annual TMV check at the sink — probe in the flow, reading dead on 41°C. Cold inlet then isolated to make sure the failsafe still cuts the hot. Dated certificate goes straight to the landlord for their HMO file.

Quarterly tank inspection on a commercial site — float valve happy, low-level alarm working, base photographed for the L8 risk log. Bit of sediment building up so I've flagged it for the next clean.

Drag the slider — this is the same drain, 12 m down the run, before and after. Cracked clay with a displaced joint on the left; smooth glossy cured patch liner on the right. No driveway dig, no reinstatement bill, customer back to normal same day.

What Clients Ask About These Jobs

Where do you cover for installs like these?

We're based in Enfield (EN2) and run 24/7 cover across north London, south Hertfordshire and west Essex — anywhere inside about an hour of base (Southgate, Palmers Green, Winchmore Hill, Cockfosters, Cheshunt, Waltham Cross, Hoddesdon, Potters Bar, Hatfield, St Albans, Epping, Loughton, Buckhurst Hill, Chigwell, Harlow and the whole of inner/outer London). Same one-hour radius covers both everyday plumbing and specialist work — water hygiene, leak detection, electric boiler installs and drain patch lining.

Are these real photos from real Pipe Assassin jobs?

Yes. Every photo on this page is from an actual install or service carried out by Pipe Assassin Plumbing — no stock photography, no AI-generated images, no filters. Each job is logged, dated and certified.

Which brands of boiler, cylinder and water heater do you fit?

We fit and service all major UK brands including Hyco, Heatrae Sadia, Ariston, Worcester Bosch, Vaillant, Stelflow, Varem, Pegler and Reliance. We carry common spares on the vans for same-day repairs on most leading models.

What certifications do your engineers hold?

Pipe Assassin Plumbing is an electric-boiler-only specialist — we are NOT Gas Safe registered and do not work on gas appliances. Our engineers are G3 certified for unvented hot water systems, TMV2 / TMV3 trained for scald-protection installations, and WRAS / Water Regulations Approved Plumber qualified for water hygiene work. For gas work you'll need a separate Gas Safe engineer.

How quickly can you carry out an install or emergency service?

Inside our 1hr Enfield radius (all London, south Herts, west Essex) we aim to be on your doorstep the same hour for active leaks, burst pipes and make-safe jobs. Planned installs — expansion vessels, TMVs, under-sink heaters, cylinder swaps — are normally booked within 48 hours.

Do you supply documentation for landlords, HMO licensing and buyer surveys?

Yes — we issue dated Legionella risk assessments to ACOP L8 / HSG274 spec, TMV recalibration certificates to BS 7942, G3 unvented commissioning paperwork, Benchmark records for electric boilers, and full WRAS-compliance notes for water-hygiene work. Every UK council HMO licensing team we've supplied has accepted our paperwork first time.

How much does a typical TMV, expansion vessel or POU heater install cost?

Replacement TMV2 valves typically start from £180 fitted, expansion vessel swaps on unvented cylinders from £220 fitted, and under-sink point-of-use electric water heater installs from £450 supplied and fitted. Final price depends on access, pipework changes and any G3 / Part G commissioning required — every quote is fixed in advance.
