Corgi TRIPCON5-C Concentrated Central Heating Leak Sealer - Clear

This is a great product.My boiler was losing it's pressure over 2-3 days. I put about 300 ml (I spilt the rest) in my four radiator system, and the pressure has been constant at 1.0 bar when the system has been off. It's been in nearly 48 hours.One comment. i read about putting into a radiator (something that sounded tricky), but my system has a filter. It was really easy to isolate the filter whe the system was off, and put it in the system that way.Overall, 20 minutes and £13 was a great relief compared to getting a plumber to check all my under floor pipes leak-hunting.Highly recommended.

It does work

Great product...Worked well for me.Had a slow leak on towel RAD.Almost zero leakage after 24 hours (looks like will be 100% sealed shortly).Product looks / smells like PVA Glue so advise shaking the bottle before putting into the system.Also BE AWARE that once it does its job (if it works for you) the boiler pressure will go up quickly... I also suspect it generally increases the boiler pressure due to changing water surface tension as my boiler pressure went up to the red bar twice even though I had let out pressure beforehand. Also be sure to open all RADs on the system to get even distribution.So far so good.

My heating system (combi boiler with 11 radiators) started loosing about half a bar of pressure every two days. Left it for two weeks while topping up the pressure every day and no stains appeared on ceilings which meant it must have been under the ground floor (also checked the boiler pressure release pipe which was dry and hence almost certainly a pipe leak). Don’t fancy ripping up carpets and floorboards yet so I added one bottle to a radiator by turning off its valves, draining it, and then using an easyfill funnel attached to the radiator to poor it in. Fired up the boiler, put the pressure back up to 1 bar, bled the radiators and it’s been perfect since. Will be interesting to see how long it lasts but I am well impressed so far.

As with other reviewers, my central heating system (Worcester condensing combi boiler, 11 radiators, small bore pipes) was losing pressure over the course of a week to ten days, and needing recharging/bleeding.Fortunately, the highest point in our central heating system is a heated towel rail, with a bleed valve on top, so adding the leak sealer was just a question of unscrewing the housing and pouring it into the already partly empty radiator via a funnel.Recharged the system, bleeding air out as necessary, then ran the heating for a few hours. 3 weeks later, and it's still bang on pressure.Job's a good 'un.

I found a very small leak in my heating system and used this to solve the problem. It took some time but did the job. It was a pain to put into the system through the header tank and I had to work very hard to flush airlocks out of the system after treatment but the end result is quieter and more efficient heating.

I bit taken back that it was white ! After fitting a replacement radiator, I could not get one of the extensions to stop leaking ( only slightly) even after 3 attempts. As I put new inhibitor a week prior I just drained about 5 litres out of the system and added this, after topping up and bleeding I ran the CH for about 2 hours. I checked the area of the leak a week later and it has stopped so I’m very pleased 😀

I'm not really in a position to comment on this as the hole I was trying to seal turned out to be a poorly soldered (not by me, I hasten to add) which had come apart and left a 10mm wide gap.The sealant wasn't really up the job of dealing with that kind of trauma.
