burst
- after 2 months boat use longitudinal crack and everything put under water - pump does not make 5 bar
Eric T.
by Eric T. Flag of Belgium 8/30/2025 Verified purchase in use on a Bavaria Yachtbau GmbH - Bavaria 40 Cruiser
This is not an expansion tank
This is an empty bottle, without an insulating membrane. The air contained is immediately compressed when pressurized. The small volume remaining in the bottle does not allow for reducing the pump cycling. This product is unusable. The presence of a membrane is essential.
