Hi I have a Pulsar underfloor heating manifold with a leaky thermostatic valve. Plumber has managed to stop leak by tightening nut but this is 2nd time it’s leaked through ceiling in few months so was hoping to renew. However plumber been unable source a replacement/ equivalent as I know Pulsar went out of business. Hoping someone on this forum can help with spares sourcing or am I stuck with replacing manifold? Thanks for any advice.
